Ensuring Safety during Auto-Tuning

Before Auto-Tuning, make sure the area around the motor and elevator are clear.

The motor may suddenly rotate during the Auto-Tuning process, which can result in personal injury if proper safety
measures are not taken beforehand.

YASKAWA ELECTRIC SIEP C710616 32A YASKAWA AC Drive L1000A Technical Manual 15

i.2 General Safety

W ARNING

DANGER

Rotational Auto-Tuning must always be performed with the motor disconnected from the load (ropes removed
from traction sheave).

If the ropes are is left mounted during Rotational Auto-Tuning, the drive will be unable to set motor parameters
correctly. This will result in erroneous operation.

Electrical Shock Hazard

Do not connect or disconnect wiring while the power is on. Never remove or install option cards or attempt to
replace the cooling fan while the drive is switched on. Make sure that the drive and all devices connected to the
drive have been shut off prior to performing and type of maintenance or wiring. After shutting off the power,
wait for at least the amount of time specified on the drive before touching any components.

The internal capacitor remains charged even after the power supply is turned off.

Failure to comply can result in serious electric shock.

Sudden Movement Hazard

Drive settings and system design may cause the elevator to begin running as soon as the power to the drive is
switched on. This can result in serious personal injury or even death.

Clear all personnel from the drive, motor, and elevator area before applying power. Secure covers, couplings, shaft
keys, and machine loads before applying power to the drive.

A brake independent of drive circuitry must be prepared by the user prior to operation.
The holding brake should be wired so that it is applied by an external sequence when a fault occurs, the power is
shut off, or an emergency switch is triggered.

When the drive faults out, the output is shut off. This, however, does not stop the motor immediately. Some type of
mechanical brake may be needed if it is necessary to halt the motor faster than the Emergency Stop function is able to.

Failure to comply could result in death or serious injury.

A separate brake should be installed to prevent an external force from rotating the motor.

Even during operation, a vertical force external to the load (such as gravity) can rotate the motor unexpectedly. To
ensure application safety, install a separate external brake.

Wire the brake sequence so that the brake applies as soon as baseblock shuts off drive output.

If the brake fails to apply immediately upon baseblock, the motor will begin to coast when baseblock shuts the drive
output, causing the elevator car to free-fall.

Confirm the drive I/O signals and external sequence before starting test run.

Failure to comply may result in death or serious injury.

Ensure start/stop and safety circuits are wired properly and in the correct state before energizing the drive.

Failure to comply could result in death or serious injury from moving equipment.

Double check the emergency stop sequence once wiring is complete. The emergency stop circuitry is crucial for
safety to ensure that the application can stop immediately.

Failing to properly verify all emergency stop wiring could result in serious personal injury.

The drive is capable of running the motor up to 120 Hz. Due to the danger of accidentally of operating at high
speed, be sure to set the upper limit for the frequency. The default setting for the maximum output frequency is
50 Hz.

Incorrect settings can cause the drive to accelerate to dangerously high speed.

Ensure there are no short circuits between the main circuit terminals (R/L1, S/L2, and T/L3) or between the
ground and main circuit terminals before restarting the drive.

Failure to comply may result in serious injury or death and will cause damage to equipment.

16 YASKAWA ELECTRIC SIEP C710616 32A YASKAWA AC Drive L1000A Technical Manual

i.2 General Safety

W ARNING

Never set the stopping method to anything other than “Ramp to stop”. Parameter b1-03 should therefore always
be set to 0.

Any other setting leaves the motor uncontrolled when the Up/Down command is removed and can cause the elevator
car to free-fall.

To avoid the motor's coasting and to ensure the motor's stopping quickly and safely, set an appropriate
Emergency Stop Ramp to C1-09.

Rapid deceleration can trigger an overvoltage fault. When faulted, the drive output shuts off, and the motor coasts.

Do not use the fault restart function unnecessarily.

Carelessly using the fault restart function leads to an unintended start of the elevator, resulting in death or serious
injury.

Ensuring Safety during Auto-Tuning

When using a PM motor for the first time, or when replacing the drive or PM motor, always make sure that
motor parameter have been set properly and the speed detection function accurately prior to operation.

Using a PM motor requires that the encoder offset be set correctly in addition to entering motor data to
corresponding parameters. If the motor, encoder, or drive is ever replaced, be sure to perform Encoder Offset
Auto-Tuning.

Insufficient torque can cause the elevator car to move in the direction of the load, or cause the motor to behave
erratically (reverse operation, stand still, sudden accelerations, etc.).

For more information, refer to the instruction manual included with the motor.

When performing Stationary Auto-Tuning for Line-to-Line Resistance with the rope mounted on the motor, the
brake must remain applied throughout the entire Auto-Tuning process. Make sure that a signal to release the
brake cannot be issued by the digital output terminals during Stationary Auto-Tuning.

Failure to comply could result in death or serious injury.

During Stationary Auto-Tuning and Stationary Auto-Tuning for Line-to-Line Resistance, voltage is applied to
the motor even before it rotates. Do not touch the motor until Auto-Tuning is completed.

Failure to comply may result in injury from electrical shock.

Ensuring Safety with PM Motors

When using a PM motor with a different speed feedback option than a PG-F3 card together with an external
brake sequence, make sure the brake is not released before Initial Magnetic Pole Search has been finished. Use
the Initial Pole Search Status signal (H2- = 61) to interlock the brake.

Failure to comply can cause the counterweight to pull on the elevator car, resulting in personal injury.

Even when the power has been shut off for a drive running a motor, voltage continues to be generated at the
motor terminals while the motor coasts to stop.

Failure to comply may result in injury from electrical shock.

Applications where the machine can still rotate even though the drive has fully stopped should have a magnetic
contactor installed to the output side of the drive.

Failure to comply may result in injury from electrical shock.

Do not allow an external force to rotate the motor beyond the maximum allowable speed, also when the drive
has been shut off.

Failure to comply may result in injury from electrical shock.

Whenever performing maintenance, inspection, or wiring on the motors, make sure to open the magnetic
contactor on the output side and make sure the motor has come to a complete stop. Next wait for time specified
in this manual before beginning to work on the motor.

Failure to comply may result in injury from electrical shock.

at least 15 minutes after power to the drive has been shut off before touching the fan to ensure that it has cooled
off enough.

Failure to comply could result in burns.

Ensuring Safety during Auto-Tuning

Rotational Auto-Tuning will not function properly if a holding brake is applied on the motor. Ensure the motor
can freely rotate before beginning Auto-Tuning.

Failure to comply could result in improper operation of the drive.

Ensuring Safety with PM Motors

When using a PM motor, never open or close the magnetic contactor while the motor is running.

Failure to comply could result in the drive damage.

Equipment Hazard

The drive's cooling fan may not run during Rescue Operation due to low voltage from the battery or UPS.

Using Rescue Operation for extended periods of time may result in an oH alarm as the heatsink temperature rises.

Set parameter E1-01 to match the input voltage of the drive. The drive input voltage (not motor voltage) must
be set in E1-01 for the protective features to function properly.

Failure to set the correct drive input voltage may result in improper drive operation.

Use the torque detection function in the drive to notify the PLC of a potential overcurrent or overload situation
before an overcurrent or overload fault is actually triggered. Use undertorque detection to detect any problems
that develop on the application side.

If the drive faults out due to overcurrent or overload, the drive output will be interrupted. The motor will start coasting,
potentially resulting in damage to the machinery or personal injury.

When replacing the control terminal board or removable terminal board, be sure to also check the value set to
parameter o2-04.

If o2-04 is set incorrectly, drive performance may be poor and protection functions may not operate properly,
potentially damaging the drive.

Install adequate branch circuit short circuit protection per applicable codes. The drive is suitable for circuits
capable of delivering not more than 100,000 RMS symmetrical amperes, 240 Vac maximum (200 V Class) and
480 Vac maximum (400 V Class).

Inadequate wiring could result in damage to the drive.

For optimal performance life, make sure the maximum output current does not exceed 150% of the drive rated
current.

Expected performance life estimates the number of drive starts at three million times. This assumes the carrier
frequency is at its default setting (8 kHz for models CIMR-L2A0018 to 2A0115, 4A0009 to 4A0091, and 5 kHz for
models CIMR-L2A0145, 2A0180, 4A0112, 4A0150) and a peak current of less than 150% of the drive rated current.

caused by a poor connection. Before reattaching the operator, make sure the front cover has been firmly fastened back
into place.

Do not connect control circuit ground terminals to the drive enclosure.

Improper drive grounding can cause control circuit malfunction.

Multi-function relay output terminals are rated at a minimum of 10 mA. If less than 10 mA is required, use the
photocoupler outputs (P1-C1, P2-C2).

Using the wrong current output level may not have the desired effect when the terminal is activated.

Do not use the negative DC bus terminal "-" as a ground terminal. This terminal is at high DC voltage potential.

Improper wiring connections could damage the drive.

Do not check signals while the drive is running.

The equipment may be damaged.

Make sure wiring to motor terminals U, V, and W connect the corresponding U/T1, V/T2, and W/T3 output
terminals on the drive.

Wiring to the wrong terminals will reverse the phase order, causing the motor to operate in reverse. This could cause
the elevator car to fall when attempting to go up.

Separate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1, V/T2, W/
T3, -, +1, +2) and other high-power lines.

Improper wiring practices could result in drive malfunction due to electrical interference.

22 YASKAWA ELECTRIC SIEP C710616 32A YASKAWA AC Drive L1000A Technical Manual

i.2 General Safety

NOTICE

The signal lines between the drive and the operator station or peripheral equipment should not exceed 50
meters when using an analog signal from a remote source to supply the speed reference.

Failure to comply could result in poor system performance.

Do not connect magnetic contactors to the output motor circuits without proper sequencing.

Improper sequencing of output motor circuits could result in damage to the drive.

Use a magnetic contactor (MC) to ensure that power to the drive can be completely shut off when necessary.

The MC should be wired so that it opens when a fault output terminal is triggered.

Prevent foreign matter such as metal shavings or wire clippings from falling into the drive during drive
installation and project construction.

Failure to comply could result in damage to the drive.

Place a temporary cover over the top during installation. Be sure to remove the temporary cover before start-up, as the
cover will reduce ventilation and cause the unit to overheat.

A motor connected to a PWM drive may operate at a higher temperature than motor supplied from the normal
power supply and the wider operating speed range may affect the motor cooling capacity.

Ensure that the motor is suitable for drive duty and/or the motor service factor is adequate to accommodate the
additional heating with the intended operating conditions.

Operating the motor in the low-speed range diminishes the cooling effects, increases motor temperature, and
may lead to motor damage by overheating.

Reduce the motor torque in the low-speed range whenever using a standard blower cooled motor. If 100% torque is
required continuously at low speed, consider using a special drive or vector-control motor. Select a motor that is
compatible with the required load torque and operating speed range.

The speed range for continuous operation differs according to the lubrication method and motor manufacturer.

If the motor is to be operated at a speed higher than the rated speed, consult with the manufacturer. Continuously
operating an oil-lubricated motor in the low-speed range may result in burning.

Motor vibration may increase when operating a machine in variable-speed mode, if that machine previously
operated at a constant speed.

Install vibration-proof rubber on the motor base.

The motor may require more acceleration torque with drive operation than with a commercial power supply.

Set a proper V/f pattern by checking the load torque characteristics of the elevator to be used with the motor.

Never lift the drive up while the cover is removed.

This can damage the terminal board and other components.

Do not expose the drive to halogen group disinfectants.

Failure to comply may cause damage to the electrical components in the drive.

Do not pack the drive in wooden materials that have been fumigated or sterilized.

Do not sterilize the entire package after the product is packed.

◆ Application Notes

■ Selection

Drive Capacity

The output current should not exceed 150% of the drive rated current. Select a drive that can output enough current when
accelerating a load at 100%.

For specialized motors, make sure that the motor rated current is less than rated output current for the drive.

Starting Torque

The startup and acceleration characteristics of the motor are restricted to the drive's overload current rating (150% rated
current for 60 s).

The overload rating for the drive determines the starting and accelerating characteristics of the motor. Expect lower
torque than when running from line power. To get more starting torque, use a larger drive or increase both the motor and
drive capacity.

■

Settings

DC Injection Braking

Motor overheat can result if there is too much current used during DC Injection Braking, or if the time for DC Injection
Braking is too long.

Acceleration and Deceleration Ramp

Acceleration and deceleration ramp for the motor are determined by the how much torque can be generated, the amount

of load torque, and the inertia moment ( ). A faster acceleration ramp may trigger the drive's Stall Prevention function,

which in turn may lower the acceleration ramp. Lowering the acceleration ramp can eliminate the need for Stall
Prevention, thus ensuring the elevator car moves at the designated acceleration ramp. For a higher acceleration ramp
without triggering Stall Prevention, select a drive with a larger capacity.

■ General Handling

Selecting a Circuit Breaker or Earth Leakage Circuit Breaker

Yaskawa recommends installing an ELCB (Earth Leakage Circuit Breaker) to the power supply side. The ELCB should
be designed for use with an AC drive (e.g. Type B according to IEC 60755).

Select a MCCB (Molded Case Circuit Breaker) or ELCB with a rated current that is 1.5 to 2 times higher than the rated
current of the drive in order to avoid nuisance trips caused by harmonics in the drive input current. Also refer to

Installing a Molded Case Circuit Breaker (MCCB) on page 284.

Magnetic Contactor Installation

Use a magnetic contactor (MC) on the power supply side to ensure that power to the drive can be completely shut off
when necessary. The MC should be wired so that it opens when a fault output terminal is triggered.

Do not use a magnetic contactor on the power supply side to frequently start and stop the motor. Failure to comply could
result in damage to the drive.

Inspection and Maintenance

Capacitors in the drive take time to discharge even after the power has been shut off. After shutting off the power, wait
for at least the amount of time specified on the drive before touching any components.

The heatsink can become quite hot during operation, and proper precautions should be taken to prevent burns. When
replacing the cooling fan, shut off the power and wait at least 15 minutes to be sure that the heatsink has cooled down.

Even when the power has been shut off for a drive running a PM motor, voltage continues to be generated at the motor
terminals while the motor coasts to stop. Take the precautions described below to prevent shock and injury:

• Applications where the machine can still rotate even though the drive has fully stopped should have a magnetic
contactor installed to the output side of the drive.

• Do not allow an external force to rotate the motor beyond the maximum allowable speed, also when the drive has been
shut off.

24 YASKAWA ELECTRIC SIEP C710616 32A YASKAWA AC Drive L1000A Technical Manual

i.2 General Safety

• Wait for at least the time specified on the warning label after opening the magnetic contactor on the output side before
inspecting the drive or performing any maintenance.

• Do not open and close the load switch while the motor is running, as this can damage the drive.

• If the motor is coasting, make sure the power to the drive is turned on and the drive output has completely stopped
before closing the motor contactor.

Wiring

All wire ends should use ring terminals for UL/cUL compliance. Use only the tools recommended by the terminal
manufacturer for crimping.

◆ Notes on Motor Operation

■ Using a Standard Motor

Insulation Tolerance

Consider voltage tolerance levels and insulation in applications with an input voltage of over 440 V or particularly long
wiring distances. Contact Yaskawa or your Yaskawa agent for consultation.

High Speed Operation

Problems may occur with the motor bearings and dynamic balance of the machine when operating a motor beyond its
rated speed. Contact the motor or machine manufacturer.

Torque Characteristics

Torque characteristics differ compared to operating the motor directly from line power. The user should have a full
understanding of the load torque characteristics for the application.

Vibration and Shock

L1000A lets the user choose between high carrier PWM control and low carrier PWM. Selecting high carrier PWM can
help reduce motor oscillation.

Take particular caution when using a variable speed drive for an elevator that is conventionally run from line power at a
constant speed. If resonance occurs, shock-absorbing rubber should be installed around the base of the motor.

Audible Noise

Noise created during run varies by the carrier frequency setting. When using a high carrier frequency, audible noise from
the motor is comparable to the motor noise generated when running from line power. Operating above the rated r/min,
however, can create unpleasant motor noise.

■

Using a PM Motor

• Contact Yaskawa or your Yaskawa agent if you plan to use any PM motor not endorsed by Yaskawa.

• When using a holding brake, release the brake prior to starting the motor. Failure to set the proper timing can result in
speed loss.

• When using a PM motor for the first time, or when replacing the drive or PM motor, always make sure that motor
parameter have been set properly and the speed detection function accurately prior to operation.
Using a PM motor requires that the encoder offset be set correctly in addition to entering motor data to corresponding
parameters. If the motor, encoder, or drive is ever replaced, be sure to reset the value for the encoder offset.

• When using a PM motor with a different speed feedback option than a PG-F3 card together with an external brake
sequence, make sure the brake is not released before Initial Magnetic Pole Search has been finished. Use the Initial
Pole Search Status signal (H2- = 61) to interlock the brake.
Failure to comply can cause the counterweight to pull on the elevator car, resulting in personal injury.

• The motor must be at a complete stop before performing any maintenance, inspection, or wiring.

• With a PM motor, drive output must be fully interrupted when the power is shut off and the motor is still rotating.
Failure to comply can result in personal injury.

2.1 Section Safety

W ARNING

CAUTION

NOTICE

2.1 Section Safety

Fire Hazard

Provide sufficient cooling when installing the drive inside an enclosed panel or cabinet.

Failure to comply could result in overheating and fire.

When multiple drives are placed inside the same enclosure panel, install proper cooling to ensure air entering the
enclosure does not exceed 40°C.

Crush Hazard

Whenever transporting the drive, make sure that the drive is held securely by outside case.

The drive cannot be held securely by simply grabbing on to the front cover or terminal cover. Dropping the drive can
damage the drive itself and result in personal injury.

Equipment Hazard

Prevent foreign matter such as metal shavings or wire clippings from falling into the drive during drive
installation and project construction.

Failure to comply could result in damage to the drive.
Place a temporary cover over the top during installation. Be sure to remove the temporary cover before start-up, as the
cover will reduce ventilation and cause the unit to overheat.

Observe proper electrostatic discharge (ESD) procedures when handling the drive.

Failure to comply could result in ESD damage to the drive circuitry.

Operating the motor in the low-speed range diminishes the cooling effects, increases motor temperature, and
may lead to motor damage by overheating.

Reduce the motor torque in the low-speed range whenever using a standard blower cooled motor. If 100% torque is
required continuously at low speed, consider using a special drive or vector-control motor. Select a motor that is
compatible with the required load torque and operating speed range.

The speed range for continuous operation differs according to the lubrication method and motor manufacturer.

If the motor is to be operated at a speed higher than the rated speed, consult with the manufacturer.

Continuously operating an oil-lubricated motor in the low-speed range may result in burning.

When the input voltage is 440 V or higher or the wiring distance is greater than 100 meters, pay special
attention to the motor insulation voltage or use a drive-rated motor with reinforced insulation.

Failure to comply could lead to motor winding failure.

Motor vibration may increase when operating a machine in variable-speed mode, if that machine previously
operated at a constant speed.

Install vibration-proof rubber on the motor base.

The motor may require more acceleration torque with drive operation than with a commercial power supply.

Set a proper V/f pattern by checking the load torque characteristics of the machine to be used with the motor.

Never lift the drive up while the cover is removed.

This can damage the terminal board and other components.

Avoid placing drive peripheral devices, transformers, or other electronics near the drive as the noise created can
lead to erroneous operation.

If such devices must be used in close proximity to the drive, take proper steps to shield the drive from noise.

W ARNING

3.1 Section Safety

Electrical Shock Hazard

Do not connect or disconnect wiring while the power is on. Never remove or install option cards or attempt to
replace the cooling fan while the drive is switched on. Make sure that the drive and all devices connected to the
drive have been shut off prior to performing and type of maintenance or wiring. After shutting off the power,
wait for at least the amount of time specified on the drive before touching any components.

The internal capacitor remains charged even after the power supply is turned off.

Failure to comply can result in serious electric shock.

Sudden Movement Hazard

Ensure start/stop and safety circuits are wired properly and in the correct state before energizing the drive.

Failure to comply could result in death or serious injury from moving equipment.

Double check the emergency stop sequence once wiring is complete. The emergency stop circuitry is crucial for
safety to ensure that the application can stop immediately.

Failing to properly verify all emergency stop wiring could result in serious personal injury.

Confirm the drive I/O signals and external sequence before starting test run.

Failure to comply may result in death or serious injury.

Ensuring Safety during Auto-Tuning

When using a PM motor for the first time, or when replacing the drive or PM motor, always make sure that
motor parameter have been set properly and the speed detection function accurately prior to operation.

Using a PM motor requires that the encoder offset be set correctly in addition to entering motor data to
corresponding parameters. If the motor, encoder, or drive is ever replaced, be sure to perform Encoder Offset
Auto-Tuning.

Insufficient torque can cause the elevator car to move in the direction of the load, or cause the motor to behave
erratically (reverse operation, stand still, sudden accelerations, etc.).

For more information, refer to the instruction manual included with the motor.

Electrical Shock Hazard

Do not operate equipment with covers removed.

Failure to comply could result in death or serious injury.

The diagrams in this section may show drives without covers or safety shields to show details. Be sure to reinstall
covers or shields before operating the drives and run the drives according to the instructions described in this manual.

Always ground the motor-side grounding terminal.

Improper equipment grounding could result in death or serious injury by contacting the motor case.

Do not perform work on the drive while wearing loose clothing, jewelry or without eye protection.

Failure to comply could result in death or serious injury.

<1> Remove the jumper when installing a DC reactor. Models CIMR-L2A0085 through 2A0180 and 4A0045 through 4A0150 come with a

built-in DC reactor.

<2> The drive’s protection function for the internal braking transistor needs to be disabled (L8-55 = 0) if using a regen unit such as a regen

converter or some type of braking option unit (and therefore not the internal braking transistor).

<3> If the braking resistor is equipped with a thermal relay, use this thermal relay to shut off the drive power supply in case the braking resistor

overheat occurs.
<4> Self-cooling motors do not require wiring that would be necessary with motors using a cooling fan.
<5> Supplying power to the control circuit separately from the main circuit requires a 24 V power supply (option).
<6> For control modes that do not use a motor speed feedback signal, PG option card wiring is not necessary.
<7> This figure shows an example of a sequence input to S1 through S8 using a non-powered relay or an NPN transistor. Install the wire link

between terminals SC-SP for Sink mode and SC-SN for Source mode. Leave it out for external power supply. Never short terminals SP and

SN as doing so will damage the drive.
<8> The maximum output current capacity for the +V and -V terminals on the control circuit is 20 mA. Never short terminals +V, -V, and AC, as

this can cause erroneous operation or damage the drive.

3.2 Standard Connection Diagram

<9> Enable the termination resistor in the last drive in a MEMOBUS network by setting DIP switch S2 to the ON position.
<10> The sink/source setting for the Safe Disable input is the same as with the sequence input. Jumper S3 has the drive set for an external power

supply. When not using the Safe Disable input feature, remove the jumper shorting the input and connect an external power supply. Refer to

Sinking/Sourcing Mode Selection for Safe Disable Inputs on page 69 for instructions.

<11> Disconnect the wire jumper between H1 - HC and H2 - HC when utilizing the Safe Disable input.
<12> Monitor outputs work with devices such as analog frequency meters, ammeters, voltmeters, and wattmeters. They are not intended for use as

a feedback-type of signal.

<13> Note that if the drive is set to trigger a fault output whenever the fault restart function is activated (L5-02 = 1), then a sequence to interrupt

power when a fault occurs will result in shutting off the power to the drive as the drive attempts to restart itself. The default setting for L5-02
is 0 (fault output not active during restart attempt).

<14> Be sure to use fault contact outputs MA, MB, and MC. Wire these terminals so that a fault will open the safety chain and interrupt drive

output.

<15> When the Programming Mode and editing parameter settings, L1000A will not accept an Up/Down command. If the drive still will not run

when an Up/Down command has been entered but no fault is present, then use the "Drive ready" signal (the default setting for terminal M5­M6) to interlock components.

Note: 1. The drive should be implemented in the system in a way so that a drive fault causes the safety chain to open. Always use terminal

MA-MB-MC for this purpose.

2. Even though no fault occurs, the drive can not be started under certain conditions, e.g. when the Digital Operator is left in the
Programming Mode. Use the “Drive Ready” output (default set to terminals M5-M6) to interlock operation in such situations.

WARNING! Sudden Movement Hazard. Ensure start/stop and safety circuits are wired properly and in the correct state before
energizing the drive. Failure to comply could result in death or serious injury from moving equipment.

WARNING! When using the automatic fault restart function while the wiring is made to shut off the power supply when a drive fault
occurs, make sure the drive is set not to trigger a fault output during fault restart (L5-02=0, default). Otherwise the fault restart function
can not work properly.

3.7 Main Circuit Wiring

This section describes the functions, specifications, and procedures required to safely and properly wire the main circuit
in the drive.

NOTICE: Do not solder the ends of wire connections to the drive. Soldered wiring connections can loosen over time. Improper wiring
practices could result in drive malfunction due to loose terminal connections.

◆ Wire Gauges and Tightening Torque

Select the appropriate wires and crimp terminals from Ta bl e 3 .2 through Table 3.3.

Note: 1. Wire gauge recommendations based on drive continuous current ratings using 75°C 600 Vac vinyl-sheathed wire assuming ambient

temperature within 40°C and wiring distance less than 100 m.

2. Terminals B1, B2, +1, +2, and +3, are for connecting a DC reactor, braking resistor or DC power supply. Do not connect other
nonspecific devices to these terminals.

• Consider the amount of voltage drop when selecting wire gauges. Increase the wire gauge when the voltage drop is
greater than 2% of motor rated voltage. Ensure the wire gauge is suitable for the terminal block. Use the following
formula to calculate the amount of voltage drop:

Line drop voltage (V) = 3 × wire resistance (Ω/km) × wire length (m) × current (A) × 10

• Refer to instruction manual TOBPC72060000 for braking unit or braking resistor unit wire gauges.

• Use terminal +1 and the negative terminal when connecting a braking resistor, regenerative converter, or a regen unit.

• Refer to UL Standards Compliance on page 376 for information on UL compliance.

◆ Main Circuit Terminal and Motor Wiring

This section outlines the various steps, precautions, and checkpoints for wiring the main circuit terminals and motor
terminals.

NOTICE: Make sure wiring to motor terminals U, V, and W connect the corresponding U/T1, V/T2, and W/T3 output terminals on the
drive. Wiring to the wrong terminals will reverse the phase order, causing the motor to operate in reverse. This could cause the
elevator car to fall when attempting to go up.

NOTICE: Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits. Failure to comply could result in
damage to the drive, phase-advancing capacitors, LC/RC noise filters or electric leakage circuit breakers.

NOTICE: Do not connect the AC power line to the output motor terminals of the drive. Failure to comply could result in death or serious
injury by fire as a result of drive damage from line voltage application to output terminals.

NOTICE: Make sure the motor contactor sequence is designed to only open or close the motor contactor when there is no voltage
output from the drive.

■ Cable Length Between Drive and Motor

Voltage drop along the motor cable may cause reduced motor torque when the wiring between the drive and the motor is
too long, especially at low frequency output. This can also be a problem when motors are connected in parallel with a
fairly long motor cable. Drive output current will increase as the leakage current from the cable increases. An increase in
leakage current may trigger an overcurrent situation and weaken the accuracy of the current detection.

Adjust the drive carrier frequency according to Table 3.4. If the motor wiring distance exceeds 100 m because of the
system configuration, reduce the ground currents. Refer to C6-03: Carrier Frequency on page 149.

Table 3.4 Cable Length Between Drive and Motor

Cable Length 50 m or less 100 m or less Greater than 100 m

Carrier Frequency 15 kHz or less 5 kHz or less 2 kHz or less

■ Ground Wiring

Follow the precautions to wire the ground for one drive or a series of drives.

WARNING! Electrical Shock Hazard. Always use a ground wire that complies with technical standards on electrical equipment and
local installation regulations. Minimize the length of the ground wire. Improper equipment grounding may cause dangerous electrical
potentials on equipment chassis, which could result in death or serious injury.

WARNING! Electrical Shock Hazard. Be sure to ground the drive ground terminal (200 V class: Ground to 100 Ω or less, 400 V class:
Ground to 10 Ω or less). Improper equipment grounding could result in death or serious injury by contacting ungrounded electrical
equipment.

NOTICE: Do not share the ground wire with other devices requiring a large amount of current for operation. Improper equipment
grounding could result in drive or equipment malfunction due to electrical interference.

NOTICE: When using more than one drive, ground multiple drives according to instructions. Improper equipment grounding could
result in abnormal operation of drive or equipment.

Refer to Figure 3.18 when using multiple drives. Do not loop the ground wire.

Figure 3.18

Figure 3.18 Multiple Drive Wiring

■ Wiring the Main Circuit Terminal

WARNING! Electrical Shock Hazard. Shut off the power supply to the drive before wiring the main circuit terminals. Failure to comply
may result in death or serious injury.

Wire the main circuit terminals after the terminal board has been properly grounded.

Models CIMR-L2A0018 through 0075 and 4A0009 through 0039 have a cover placed over the DC bus and braking
circuit terminals prior to shipment to help prevent miswiring. Cut away covers as needed for terminals using wire cutters.

Figure 3.19

A – Protecting Cover

Figure 3.19 Protecting Cover to Prevent Miswiring (CIMR-L2A0047)

■ Main Circuit Connection Diagram

Refer to Main Circuit Connection Diagram on page 53 when wiring terminals on the drive’s main power circuit.

WARNING! Fire Hazard. The braking resistor connection terminals are B1 and B2. Do not connect braking resistors to any other
terminals. Improper wiring connections could cause the braking resistor to overheat and cause death or serious injury by fire. Failure to
comply may result in damage to the braking circuit or drive.

4.1 Section Safety

DANGER

W ARNING

4.1 Section Safety

Ensuring Safety during Auto-Tuning

Before Auto-Tuning, make sure the area around the motor and elevator are clear.

The motor may suddenly rotate during the Auto-Tuning process, which can result in personal injury if proper safety
measures are not taken beforehand.

Rotational Auto-Tuning must always be performed with the motor disconnected from the load (ropes removed
from traction sheave).

If the ropes are left mounted during Rotational Auto-Tuning, the drive will be unable to set motor parameters correctly.

This will result in erroneous operation.

Electrical Shock Hazard

Do not connect or disconnect wiring while the power is on. Never remove or install option cards or attempt to
replace the cooling fan while the drive is switched on. Make sure that the drive and all devices connected to the
drive have been shut off prior to performing and type of maintenance or wiring. After shutting off the power,
wait for at least the amount of time specified on the drive before touching any components.

The internal capacitor remains charged even after the power supply is turned off.

Failure to comply can result in serious electric shock.

Ensuring Safety with PM Motors

When using a PM motor with a different speed feedback option than a PG-F3 card together with an external
brake sequence, make sure the brake is not released before Initial Magnetic Pole Search has been finished. Use
the Initial Pole Search Status signal (H2- = 61) to interlock the brake.

Failing to comply can cause the counterweight to pull on the elevator car, resulting in personal injury.

Whenever performing maintenance, inspection, or wiring on the motors, make sure to open the magnetic
contactor on the output side and make sure the motor has come to a complete stop. Next wait for time specified
in this manual before beginning to work on the motor.

Failure to comply may result in injury from electrical shock.

If the motor is coasting, make sure the power to the drive is turned on and the drive output has completely
stopped before closing the motor contactor.

Failure to comply may result in injury from electrical shock.

W ARNING

CAUTION

Sudden Movement Hazard

The drive is capable of running the motor up to 120 Hz. Due to the danger of accidentally of operating at high
speed, be sure to set the upper limit for the frequency. The default setting for the maximum output frequency is
50 Hz.

Incorrect settings can cause the drive to accelerate to dangerously high speed.

Never set the stopping method to anything other than "Ramp to stop". Parameter b1-03 should therefore
always be set to 0.

Any other setting leaves the motor uncontrolled when the Up/Down command is removed and can cause the elevator
car to free-fall.

Do not use the fault restart function unnecessarily.

Carelessly using the fault restart function leads to an unintended start of the elevator, resulting in death or serious
injury.

A separate holding brake should be used. The holding brake should be wired so that it is closed by an external
sequence when a fault occurs, the power is shut off, or an emergency switch is triggered.

Failure to comply could result in death or serious injury.

Precautions should be taken on the machine side to ensure that load can not fall or slip.

Failure to take proper safety precautions can result in serious injury.

Electrical Shock Hazard

Do not operate equipment with covers removed.

Failure to comply could result in death or serious injury.

The diagrams in this section may include drives without covers or safety shields to illustrate details. Be sure to reinstall
covers or shields before operating the drives and run the drives according to the instructions described in this manual.

Do not remove covers or touch circuit boards while the power is on.

Failure to comply could result in death or serious injury.

Preventing Injury

Check the area thoroughly around the motor and elevator before starting to operate the application.

Failure to comply can result in personal injury.

A separate emergency stop switch should be installed separately from drive circuitry (the drive's own
emergency stop function is enabled only when it has been assigned to one of the input terminals).

Failure to comply may result in personal injury.

Reset alarms and faults only after making sure that the Up/Down command has also been removed.

Failure to comply can result in personal injury.

Preventing Burns

Never touch the heatsink on the drive, as it can reach high temperatures. When replacing the cooling fan, wait
at least 15 minutes after power to the drive has been shut off before touching the fan to ensure that it has cooled
off enough.

Failure to comply could result in burns.

YASKAWA ELECTRIC SIEP C710616 32A YASKAWA AC Drive L1000A Technical Manual 77

4.1 Section Safety

NOTICE

Ensuring Safety during Auto-Tuning

Rotational Auto-Tuning will not function properly if a holding brake is applied on the motor. Ensure the motor
can freely rotate before beginning Auto-Tuning.

Failure to comply could result in improper operation of the drive.

Equipment Hazard

Do not check signals while the drive is running.

The equipment may be damaged.

The drive's cooling fan may not run during Rescue Operation due to low voltage from the battery or UPS.

Using Rescue Operation for extended periods of time may result in an oH alarm as the heatsink temperature rises.

Set parameter E1-01 to match the input voltage of the drive. The drive input voltage (not motor voltage) must
be set in E1-01 for the protective features to function properly.

Failure to set the correct drive input voltage may result in improper drive operation.

Use the torque detection function in the drive to notify the PLC of a potential overcurrent or overload situation
before an overcurrent or overload fault is actually triggered. Use undertorque detection to detect any problems
that develop on the application side.

If the drive faults out due to overcurrent or overload, the drive output will be interrupted. The motor will start coasting,
potentially resulting in damage to the machinery or personal injury.

When replacing the control terminal board or removable terminal board, be sure to also check the value set to
parameter o2-04.

If o2-04 is set incorrectly, drive performance may be poor and protection functions may not operate properly,
potentially damaging the drive.

◆ Power On

Before turning on the power supply

• Make sure all wires are connected properly. Also make sure motor phases are connected in the right sequence.

• Make sure that no screws, loose wire ends, or tools are left in the drive.

• If an encoder option card is used make sure the encoder is wired correctly and the power supply on the option card is
set according to the encoder specification.

After turning the power on, the drive mode display should appear and no fault or alarm should be displayed. In case of
any error refer to Drive Alarms, Faults, and Errors on page 224.

◆ Control Mode Selection

When the drive is first powered up, one of the four control modes must be selected to match the application. Note that
Closed Loop Vector modes require encoder feedback cards. The table below indicates possible control modes depending
on the motor type and shows the required encoder feedback card.

Machine Type Control Mode A1-02 setting Encoder Option Card

Induction motor without encoder

Induction motor with incremental encoder Closed Loop Vector Control 3 PG-B3 / PG-X3

V/f Control 0 No card required

Open Loop Vector Control 2 No card required

Closed Loop Vector Control for PM motors 7 PG-F3

◆ Motor Rotation Direction Setup

Depending on the elevator configuration it might be necessary to change the motor direction in order to have the elevator
traveling up when the Up command is given to the drive. Do the following to check the motor rotation direction.

• The drive puts out voltage in U-V-W phase sequence when an Up command is input. Check the motor rotation with
this phase sequence (for most motors clockwise seen from the shaft side).

• If the motor drives the elevator in up direction with a U-V-W sequence, make sure parameter b1-14 is set to 0.

• If the motor drives the elevator in down direction with a U-V-W sequence, set parameter b1-14 is set to 1.

Note: Always perform motor rotation direction setup prior to setting the encoder rotation direction.

◆ Encoder Setup

■ Encoder Resolution Setup

Set the encoder resolution (incremental signal in case of absolute encoders with Sin/Cos tracks) in parameter F1-01.

Encoder Rotation Direction Setup

■

Perform the following steps to make sure the encoder rotation direction is set up correctly in the drive.

If information about the signal sequence of the encoder are available

1. Check the sequence of encoder phases A and B when the motor drives the elevator in up direction.

2. If the encoder A phase leads phase B, make sure F1-05 is set to 0.

3. If the encoder B phase leads phase A, make sure F1-05 is set to 1.

If no information about the signal sequence of the encoder are available

1. Turn the motor manually in elevator up direction while checking the value of monitor U1-05.

2. If the value in U1-05 is positive, the set encoder direction is correct.

3. If the value in U1-05 is negative, alter the setting of parameter F1-05.

Note: Always set the motor rotation direction prior to the encoder rotation direction. Refer to Motor Rotation Direction Setup on

page 91.

When using setting 4 to 6 certain mechanical data have to be programmed to the drive prior to changing o1-03. Perform
the following steps.

1. Make sure motor data are set up correctly. Verify the setting of the maximum output frequency in parameter E1-04 and
the setting for the number of motor poles in parameter E2-04 or E5-04.

2. Set the traction sheave diameter in units of mm to parameter o1-20.

3. Set the correct roping to parameter o1-21.

4. If a mechanical gear is used, set the gear ratio (n

Motor/nTraction Sheave

) to parameter o1-22. If a gearbox is not used, make

sure o1-22 is set to 1.0.

5. Change parameter o1-03 to setting 4 or 5. The unit and setting values of related parameters will be changed
automatically.

◆ Types of Auto-Tuning

The drive offers different types of Auto-Tuning for induction motors and permanent magnet motors. The type of Auto­Tuning used differs further based on the control mode and other operating conditions. Refer to the tables below to select
the type of Auto-Tuning that bests suits the application. Directions on how to execute Auto-Tuning are listed in Start-Up

Flowcharts on page 89.

Note: The drive will only show Auto-Tuning parameters that are valid for the control mode that has been set to A1-02. If the control

mode is for an induction motor, the Auto-Tuning parameters for PM motors will not be available. If the control mode is for a PM
motor, the Auto-Tuning parameters for induction motors will not be available.

■ Auto-Tuning for Induction Motors

This feature automatically sets the V/f pattern and motor parameters E1- and E2- for an induction motor. In
Closed Loop Vector, some F1- parameters for speed feedback detection are also set up.

• Rotational Auto-Tuning gives the most accurate results, and is therefore highly recommended if
possible.

• Motor must run freely or with light load (<30%), i.e. ropes have to be removed.

• Motor test report or data sheet is not available.

• Automatically calculates motor parameters needed for vector control.

• Use if ropes can not be removed. Note that the accuracy is less then with Rotational Auto-tuning.

• Used for V/f Control or in vector control modes when the drive was set up properly before and the
motor cable has changed.

• Used in V/f control if drive and motor capacities differ.

• Should not be used for any vector control modes unless the motor cable has changed.

• A motor test report is available. The no-load current and the rated slip must be entered from the test
report, all other motor-related parameters are calculated automatically.

• Use if ropes can not be removed and if slip and no-load current data are available.

■ Encoder Offset Auto Tuning

Encoder Offset Tuning is used for PM motors (A1-02=7). It measures the angle between the encoder zero position and
the rotor magnet orientation. It needs to be performed when:

• a drive is setup the first time.

• after initialization.

• when the motor rotation direction has been changed (b1-14).

• when the encoder rotation direction has been changed (F1-05).

• when the encoder has been replaced.

Before performing Encoder Offset Tuning the motor and encoder data must be set properly.

Table 4.9 Types of Auto-Tuning for Encoder Offset

sets parameters needed for Initial Magnet Pole Search (n8-36, n8-37).

• When using the rescue operation mode, perform this tuning to let the drive automatically set the parameters needed for Initial
Magnet Pole Search with power supply from a battery or UPS (n8-81, n8-82).

• Must be performed when using an incremental encoder.

Important: When using a PG-X3 card with an incremental encoder and this tuning fails, the motor can not be driven using and incre­mental encoder. Change the encoder to an absolute encoder.

• Tunes the encoder offset without rotating the motor.

• If the encoder offset can not be tuned properly by this method run Rotating Encoder Offset Tuning.

• Tunes the encoder offset while rotating the motor.

• Motor and mechanical system must be uncoupled (ropes must be removed from traction sheave).

◆ Before Auto-Tuning the Drive

Check the items below before Auto-Tuning the drive.

■

General Auto-Tuning Preparations and Precautions

WARNING! When performing Rotational Auto-Tuning for motor data or encoder offset, always uncouple the motor from the

mechanical system (remove ropes from traction sheave). Performing Rotational Auto-Tuning with the mechanical system connected to
the motor can cause hazardous situations, injury to personnel and damage to the equipment.

WARNING! Electrical Shock Hazard. When executing Stationary Auto-Tuning for motor data or encoder offset, the motor does not
rotate, however, power is applied. Do not touch the motor until Auto-Tuning is completed. Failure to comply may result in dead or
serious injury from electrical shock.

WARNING! Sudden Movement Hazard. Do not release the mechanical brake during Stationary Auto-Tuning. Inadvertent brake
release may cause damage to equipment or injury to personnel. Ensure that the mechanical brake release circuit is not controlled by
the drive multi-function digital outputs exclusively.

• Always try to perform Rotational Auto-Tuning as it gives more accurate results than Non-Rotating Auto-Tuning.
Rotation Auto-Tuning should be performed whenever the motor can be uncoupled from the elevator mechanical
system (remove ropes from traction sheave). When motor and mechanical system can not be uncoupled, use a
Stationary Auto-Tuning method.

• Make sure that the mechanical brake is kept applied for all Stationary Auto-Tuning methods. Make sure to release the
brake for all Rotational Auto-Tuning methods.

• Motor contactors must be closed during the Auto-Tuning process.

• H1 and H2 signals must be ON when performing Auto-Tuning.

• A digital input programmed for Baseblock (H1-=8/9) must be set so that the drive is not in a baseblock condition.

• Confirm that the motor is mechanically fixed. Do not touch the motor until the Auto-Tuning process is complete.
Voltage is applied to the motor during the tuning process, even though the motor may not be rotating.

• Auto-Tuning can be cancelled any time by pressing the STOP key on the digital operator.

• Auto-Tuning requires the user to input data from the motor nameplate or motor test report. Make sure this data is
available before Auto-Tuning the drive.

• For best performance, the drive input supply voltage must be greater than the motor rated voltage.

Note: Better performance is possible when using a motor with a base voltage that is 20 V (40 V for 400 V class models) lower than the

input supply voltage. This is particularly important when operating the motor above 90% of base speed, where high torque
precision is required.

• Make sure the area around the motor is clear of personnel and any equipment before starting the tuning.

• The motor should be fully stopped. Personal injury may result if the motor is already in motion when Auto-Tuning is
executed.

• For all Rotating Auto-Tuning modes remove the lock key from the motor shaft when tuning a motor with no gear or
traction sheave mounted.

• Table 4 .1 0 describes digital input and output terminal operation while Auto-Tuning is executed.
