Product Description
The P1000 Bypass provides a means of bypassing the drive while allowing the motor to operate at full speed, directly from
the AC line. It incorporates an AC Drive and a three-contactor bypass arrangement in a single UL listed enclosure. The two
electrically interlocked IEC rated drive output and bypass contactors isolate the drive from the load when operating in Bypass
mode. An IEC rated drive input contactor also isolates the drive from the line when operating in Bypass mode.
Control logic provides industry standard Hand/Off/Auto functions, BAS Interlock, and safety circuit interlocks in both Drive
and Bypass operating modes.
Bypass components include: a fused 120 Vac control circuit transformer, drive input fuses, motor overload, and an HOA
keypad with LCD display.
The P1000 drive, a component of the P1000 Bypass package, is a pulse width modulated drive for three-phase AC induction
motors. This type of drive is also known as an adjustable frequency drive, variable frequency drive, AC Drive, AFD, ASD,
VFD, and inverter.
The drive is a variable torque AC drive, designed specifically for fans, blowers, and pumps.
The P1000 Bypass has BACnet and Modbus® embedded communications.
The LCD keypad/operator is equipped with Hand/Off/Auto functions. Optional DriveWizard software allows upload/
download, as well as graphing and monitoring of drive parameters from a PC for ease of drive management.
Built-in PI control eliminates the need for closed loop output signals from a building automation system. It includes feedback
display, inverse, square root and differential control functions, and maintains setpoint for closed loop control of fans and pumps
for pressure, flow, or temperature regulation. An additional independent PI control is also provided for external devices.

Drive Capacity
For specialized motors, make sure that the motor rated current is less than the rated output current for the drive.
When running more than one motor in parallel from a single drive, the capacity of the drive should be larger than [total motor
rated current × 1.1].
Starting Torque
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.
Emergency Stop
During a drive fault condition, the output shuts off but the motor does not stop immediately. A mechanical brake may be
required when it is necessary to stop the motor faster than the ability of the Fast Stop function of the drive.
Options
NOTICE: The B1, B2, ⊖, ⊕1, ⊕2, and ⊕3 terminals are used to connect optional drive-specific compatible devices only. Connecting non-
Yaskawa-approved devices to these terminals may damage the drive.
Repetitive Starting/Stopping
Laundry machines, punching presses, and other applications with frequent starts and stops often approach 150% of their rated
current values. Heat stress generated from repetitive high current will shorten the life span of the IGBTs.
Yaskawa recommends lowering the carrier frequency, particularly when audible noise is not a concern. It is beneficial to
reduce the load, increase the acceleration and deceleration times, or switch to a larger drive to help keep peak current levels
under 150%. Be sure to check the peak current levels when starting and stopping repeatedly during the initial test run, and
make adjustments accordingly.
Installation
n
Enclosure Panels
Keep the drive in a clean environment by installing the drive in an enclosure panel or selecting an installation area free of
airborne dust, lint, and oil mist. Be sure to leave the required space between drives to provide for cooling, and take proper
measures so the ambient temperature remains within allowable limits and keep flammable materials away from the drive.
Yaskawa offers protective designs for drives that must be used in areas subjected to oil mist and excessive vibration. Contact
Yaskawa or your Yaskawa agent for details.
Installation Direction
NOTICE: Install the drive upright as specified in the manual. Refer to Mechanical Installation on page 38 for more information on
installation. Failure to comply may damage the drive due to improper cooling.
Settings
n
Upper Limits
NOTICE: The drive is capable of running the motor up to 400 Hz. Be sure to set the upper limit for the frequency of the drive to prevent the
possible danger of accidentally operating equipment at higher than rated speed. The default setting for the maximum output frequency is
60 Hz.
DC Injection Braking
NOTICE: Excessive current during DC Injection Braking and excessive duration of DC Injection Braking can cause motor overheat.
YASKAWA SIEP YAIP1B 01A YASKAWA AC Drive – P1000 Bypass Technical Manual

i.2 General Safety
Acceleration/Deceleration Times
Acceleration and deceleration times are affected by the amount of torque generated by the motor, the load torque, and the
inertia moment. Set a longer accel/decel time when Stall Prevention is enabled. The accel/decel times are lengthened for as
long as the Stall Prevention function is in operation. Install one of the available braking options or increase the capacity of the
drive for faster acceleration and deceleration.
General Handling
n
Wiring Check
NOTICE: Do not connect power supply lines to output terminals U/T1, V/T2, or W/T3. Failure to comply will destroy the drive. Be sure to
perform a final check of all sequence wiring and other connections before turning on the power and also check for short circuits on the
control terminals, which may damage the drive.
Inspection and Maintenance
WARNING! Electrical Shock Hazard. Capacitors in the drive do not immediately discharge after shutting off the power. Wait for at least the
amount of time specified on the drive before touching any components after shutting off the power. Failure to comply may cause injury to
personnel from electrical shock.
Transporting the Drive
NOTICE: Never steam clean the drive. During transport, keep the drive from coming into contact with salts, fluorine, bromine, phthalate
ester, and other such harmful chemicals.
u
Motor Application Precautions
Insulation Tolerance
NOTICE: Consider motor voltage tolerance levels and motor insulation in applications with an input voltage of over 480 V or particularly
long wiring distances.
High-Speed Operation
NOTICE: 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
The drive allows selection of high carrier PWM control and low carrier PWM. Selecting high carrier PWM can help reduce
motor oscillation.
Take particular caution when adding a variable speed drive to an application running a motor from line power at a constant
speed. If resonance occurs, install shock-absorbing isolation mounts around the base of the motor and enable the Jump
frequency selection to prevent continuous operation in the resonant frequency range.
Audible Noise
The audible noise of the motor varies based on the carrier frequency setting. However, drive current derating may be required.
When using a high carrier frequency, audible noise from the motor is comparable to the motor noise generated when running
from line power.
Specialized Motors
n
Multi-Pole Motor
The rated current of a multi-pole motor differs from that of a standard motor, so be sure to check the maximum current when
selecting a drive. Always stop the motor before switching between the number of motor poles. The motor will coast to stop if
a regen overvoltage (ov) fault occurs or if overcurrent (oC) protection is triggered.
Submersible Motor
The rated current of a submersible motor is greater than that of a standard motor, so select the drive capacity accordingly. Use
a motor cable large enough to avoid decreasing the maximum torque level from voltage drop caused by a long motor cable.
Explosion-Proof Motor
The motor and the drive must be tested together to be certified as explosion-proof. The drive is not designed for explosionproof areas.

YASKAWA SIEP YAIP1B 01A YASKAWA AC Drive – P1000 Bypass Technical Manual
i.2 General Safety
Geared Motor
Make sure that the gear and the lubricant are rated for the desired speed range to avoid gear damage when operating at low
speeds or very high speeds. Consult with the manufacturer for applications that require operation outside the rated speed range
of the motor or gear box.
Single-Phase Motor
Variable speed drives are not designed to operate with single phase motors. Using capacitors to start the motor causes excessive
current to flow and can damage drive components. A split-phase start or a repulsion start can burn out the starter coils because
the internal centrifugal switch is not activated. The drive is for use with three-phase motors only.
Motor with Brake
Take caution when using the drive to operate a motor with a built-in holding brake. If the brake is connected to the output side
of the drive, it may not release at start due to low voltage levels, so be sure to install a separate power supply for the motor
brake. Note that motors with built-in brakes tend to generate a fair amount of noise when running at low speeds.

Input Circuit Breaker
n
Electrically located on the input power side of the bypass, the input circuit breaker and its main disconnect handle provide a
means of disconnecting the bypass from line power for equipment maintenance. The handle must be in the OFF position to
open the bypass enclosure door. The handle can be locked in the OFF position using a padlock.
Contactors
n
The P1000 Bypass is a 3-contactor bypass circuit employing IEC rated contactors in an electrically interlocked arrangement
to allow mutually exclusive operation in Drive or Bypass modes.
The control logic and “soft start” characteristic of the drive limit the drive input and output contactors to motor FLA current
or less. The bypass contactor is exposed to motor inrush current (LRA) when starting the motor across-the-line and therefore
may require a higher current rating than the drive input and output contactors.
Overload Relay
n
The adjustable thermal overload relay (OLR) provides overload protection for the motor in Drive and Bypass operating modes.
The bypass three-phase output power connection to the motor is made to the output terminals of the OLR. The OLR is set up
in the factory to be a manual reset device, requiring operator attention if an overload trip-out is experienced.
Control Power Transformer
n
A Control Power Transformer (CPT) is provided to power the P1000 Bypass 120 Vac control circuit. The VA capacity is
determined by the control circuit and optional functions specified for the unit. The CPT primary is fused in both legs, the
secondary is fused when required by NEC (transformer VA and wire size dependent). One side of the transformer secondary
is grounded to the bypass enclosure.
Electronic Bypass Control Logic
n
Operating elements such as indicating LEDs, selector buttons, and control logic are incorporated into a PCB assembly to
eliminate the potential for loose wires after shipment.
The operating elements are located on PCB A3 and the control logic PCB A2 is mounted to the left-hand side of the enclosure
and contains the control circuit field wiring terminal blocks TB1 through TB3.

WARNING
Crush Hazard
Use a dedicated lifting device when moving or positioning the drive.
Failure to comply may result in serious injury or death from falling equipment.
Use screws to securely affix the drive front cover, terminal blocks, and other drive components prior to vertical
suspension.
Failure to comply may result in serious injury or death from falling equipment.
Do not subject the bypass to vibration or impact greater than 1.96 m/s2 (0.2 G) while it is suspended by the cables.
Failure to comply may result in serious injury or death from falling equipment.
Do not attempt to flip the bypas over or leave the drive unattended while it is suspended by the wires.
Failure to comply may result in serious injury or death from falling equipment.
CAUTION
Crush Hazard
Do not carry the bypass by the front cover or the terminal cover.
Failure to comply may result in minor or moderate injury from the main body of the drive falling.
NOTICE
Equipment Hazard
Prevent foreign matter such as metal shavings or wire clippings from falling into the drive or bypass during drive
installation and project construction.
Failure to comply could result in damage to the drive and bypass. 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 bypass and drive.
Failure to comply could result in ESD damage to the drive and bypass 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.

YASKAWA SIEP YAIP1B 01A YASKAWA AC Drive – P1000 Bypass Technical Manual
2.1 Section Safety
NOTICE
When the input voltage is 480 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 or use the frequency jump function to skip a frequency resonating the
machine.
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.
The rated input current of submersible motors is higher than the rated input current of standard motors.
Select an appropriate drive according to its rated output current. When the distance between the motor and drive is long, use
a cable thick enough to connect the motor to the drive to prevent motor torque reduction.
The current rating for a motor with variable pole pitches differs from a standard motor.
Check the maximum current of the motor before selecting the drive capacity. Only switch motor poles when the motor is
stopped. Switching between motor during run will trigger overcurrent protection circuitry or result in overvoltage from
regeneration, and the motor will simply coast to stop.
Never lift or move the bypass while the cover is open.
This can damage the bypass components.

the circuit breaker option (PM) or when protected by class J or class L fuses as specified on the P1000 Bypass nameplate.
NOTICE: 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 duty motor. Failure to comply could lead to motor insulation breakdown.
NOTICE: Do not connect AC control circuit ground to drive enclosure. Improper drive grounding can cause control circuit malfunction.
Note: The minimum load for relay outputs DO-7, DO-8, DO-9, DO-10, M1-M2, M3-M4, M5-M6, and MA-MB-MC is 10 mA.
WARNING! Sudden Movement Hazard. Do not close the wiring for the control circuit unless the multifunction input terminal parameters are
properly set. Improper sequencing of run/stop circuitry could result in death or serious injury from moving equipment.
WARNING! Sudden Movement Hazard. Ensure start/stop 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. When programmed for 3-Wire control, a momentary closure
on terminal S1 may cause the drive to start.
WARNING! Sudden Movement Hazard. When using a 3-Wire sequence, set the drive to 3-Wire sequence prior to wiring the control terminals
and set parameter b1-17 to 0 so the drive will not accept a Run command at power up (default). If the drive is wired for a 3-Wire sequence
but set up for a 2-Wire sequence (default), and parameter b1-17 is set to 1 so the drive accepts a Run command at power up, the motor
will rotate in reverse direction at drive power up and may cause injury.
WARNING! Sudden Movement Hazard. Confirm the drive I/O signals and external sequence before executing the application preset
function. Executing the application preset function or setting A1-06 ≠ 0 will change the drive I/O terminal functions and may cause unexpected
equipment operation. Failure to comply may cause death or serious injury.
NOTICE: Route motor leads U/T1, V/T2, and W/T3 separate from all other leads to reduce possible interference-related issues. Failure to
comply may result in abnormal operation of bypass and nearby equipment.
NOTICE: When using the automatic fault restart function with wiring designed to shut off the power supply upon drive fault, make sure the
drive does not trigger a fault output during fault restart (L5-02 = 0, default). Failure to comply will prevent the automatic fault restart function
from working properly.

NOTICE: Do not solder the ends of wire connections to the bypass. Soldered wiring connections can loosen over time. Improper wiring
practices could result in malfunction due to loose terminal connections.
NOTICE: Do not switch the bypass input to start or stop the motor. Frequently switching the bypass on and off shortens the life of the DC
bus charge circuit and the DC bus capacitors, and can cause premature bypass failures. For the full performance life, refrain from switching
the bypass on and off more than once every 30 minutes.
u
Factory Recommended Branch Circuit Protection
WARNING! Fire Hazard. Branch Circuit protection is required to be installed according to applicable local codes and the requirements listed
on the P1000 Bypass nameplate. Failure to comply could result in fire and damage to the bypass and drive or injury to personnel. The P1000
Bypass is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical amperes, 208 Vac and 480 Vac with
the circuit breaker option or when protected by class J or class L fuses as specified on the P1000 Bypass nameplate.
Yaskawa recommends installing branch circuit protection according to maintain compliance with UL508C. Semiconductor
protective type fuses are preferred. Alternate branch circuit protection devices are also listed in this manual.

Wire Gauge and Tightening Torque Specifications
Note: 1. For 0 to 100 A, use a minimum of 60 °C - 75 °C copper wire.
2. For above 100 A, use a minimum of 75 °C copper wire.
3. 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.
• 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

Main Input Circuit and Motor Wiring
This section outlines the various steps, precautions, and checkpoints for wiring the main circuit terminals and motor terminals.
WARNING! Electrical Shock Hazard. Do not connect the AC power line to the bypass output terminals. Failure to comply could result in
death or serious injury by fire as a result of bypass damage from line voltage application to output terminals.
NOTICE: When connecting the motor to the output terminals T1, T2, and T3, the phase order for the drive and motor should match. Failure
to comply with proper wiring practices may cause the motor to run in reverse if the phase order is backward.
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 ground fault circuit interrupters.
NOTICE: Route motor leads U/T1, V/T2, and W/T3 separate from all other leads to reduce possible interference-related issues. Failure to
comply may result in abnormal operation of bypass and nearby equipment.

3.3 Main Circuit Wiring
Cable Length Between Bypass and Motor
n
Voltage drop along the motor cable may cause reduced motor torque when the wiring between the bypass 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. Bypass 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 carrier frequency according to Table 3.2. If the motor wiring distance exceeds 100 m because of the system
configuration, reduce the ground currents. Refer to C6-02: Carrier Frequency Selection on page 104.
Table 3.2 Cable Length Between Bypass and Motor
Cable Length 50 m or less 100 m or less Greater than 100 m
Carrier Frequency 12.5 kHz or less 5 kHz or less 2 kHz or less
Note: 1. When setting carrier frequency for bypasses running multiple motors, calculate cable length as the total wiring distance to all connected
Ground Wiring
n
motors.
2. Do not use a long distance shielded line if there is an overvoltage problem at start. Either lower the carrier frequency or switch on the
internal EMC filter if the power supply has a neutral ground.
Follow the precautions below when wiring the ground for one bypass or a series of bypasses.
WARNING! Electrical Shock Hazard. Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even
after the power supply is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent electric
shock, wait for at least the time specified on the warning label, once all indicators are OFF, measure for unsafe voltages to confirm the drive
is safe prior to servicing.
WARNING! Electrical Shock Hazard. Make sure the protective earthing conductor complies with technical standards and local safety
regulations. Because the leakage current exceeds 3.5 mA, IEC 61800-5-1 states that either the power supply must be automatically
disconnected in case of discontinuity of the protective earthing conductor or a protective earthing conductor with a cross-section of at least
10 mm2 (Cu) or 16 mm2 (Al) must be used. Failure to comply may result in death or serious injury.
WARNING! Electrical Shock Hazard. Always use a ground wire that complies with technical standards on electrical equipment and 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 (208 Vac bypass drive: ground to 100 Ω or less and 480
Vac bypass drive: 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 such as welding machines or large-current electrical equipment. 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 3.1 when using multiple drives. Do not loop the ground wire.
The drive ground lug (terminal
) is connected to the enclosure. The enclosure ground lug must be connected to earth ground.
The drive has a second ground lug to accept the motor ground lead.

comply may result in abnormal operation of bypass and nearby equipment.
NOTICE: Separate wiring for digital output terminals MA, MB, MC, and M1 to M6 from wiring to other control circuit lines. Improper wiring
practices could result in drive or equipment malfunction or nuisance trips.
NOTICE: Use a class 2 power supply when connecting to the control terminals. Improper application of peripheral devices could result in
drive performance degradation due to improper power supply. Refer to NEC Article 725 Class 1, Class 2, and Class 3 Remote-Control,
Signaling, and Power Limited Circuits for requirements concerning class 2 power supplies.
NOTICE: Insulate shields with tape or shrink tubing to prevent contact with other signal lines and equipment. Improper wiring practices could
result in drive or equipment malfunction due to short circuit.
NOTICE: Connect the shield of shielded cable to the appropriate ground terminal. Improper equipment grounding could result in drive or
equipment malfunction or nuisance trips.
Wire the control circuit only after terminals have been properly grounded and main circuit wiring is complete. Refer to
Terminal Wiring Guide on page 50 for details. Prepare the ends of the control circuit wiring as shown in Figure 3.6.
NOTICE: Do not tighten screws beyond the specified tightening torque. Failure to comply may result in erroneous operation, damage to the
terminal block, or cause a fire.
NOTICE: Use shielded twisted-pair cables as indicated to prevent operating faults. Improper wiring practices could result in drive or
equipment malfunction due to electrical interference.

Building Automation System Run/Stop Circuit
DI-1 (TB2-1 by default setting in Z2-01) is available to connect the normally open (N.O.) Run/Stop contact from a BAS or
other remote controller for auto mode control.
These terminals must have contact closure for the motor to run in AUTO mode.
u
Safety Interlock Circuit
DI-2 (TB2-2 by default setting in Z2-02) is provided to connect safety devices in a normally-closed series circuit, such as:
freeze up thermostats, smoke/fire sensors, high pressure limits, temperature limits or vibration detectors.
The HOA keypad will display the status “Safety Open”, and trigger a Safety Open fault if a N.C. safety circuit is not closed
between DI-2 and IG24 (TB2-10) on PCB A2 at power-up with a Run command in HAND or AUTO mode. An open circuit
between DI-2 and IG24 will prevent bypass operation.
Take one of the following steps to ensure proper operation prior to startup:
Install a N.C. safety circuit between DI-2 and IG24 on PCB A2.
1.
Install a jumper between DI-2 and IG24 (on PCB A2. A normally-closed safety circuit may also be used in place of

Building Automation System Interlock Circuit (Drive and Bypass Enable Input)
The HOA keypad will display the status “INTRLOCK OPN” and possibly a “BAS Ilock-open” alarm or “BAS Ilock TO”
fault if a N.C. safety circuit is not closed between DI-3 (TB2-3 by default setting of Z2-03) and IG24 on PCB A2 at powerup with a Run command in HAND or AUTO mode. An open circuit between TB2-3 and IG24 (TB2-10) will prevent bypass
operation.
Take one of the following steps to ensure proper operation prior to startup:
Install a N.C. BAS Interlock Circuit/Damper Interlock between DI-3 and IG24 on PCB A2.

Remote Transfer to Bypass
Terminal TB2-4 is a programmable input with a default setting of “Remote Transfer to Bypass” operation. The function of
this terminal can be changed using parameter Z2-04.
This function allows a contact closure from a BAS, between terminals TB2-4 and TB2-10, to transfer motor operation from
Drive mode to Bypass mode. An open contact allows operation in Drive mode and a closed contact allows operation in Bypass
mode.
u
Smoke Purge Operation
Terminal TB2-5 is a programmable input with a default setting of “Smoke Purge” operation. The function of this terminal can
be changed using parameter Z2-05.
This function allows a contact closure between terminals TB2-5 and TB2-10 to transfer motor operation to bypass for smoke
purge operation. The motor overload and Safety Interlock circuit are overridden during smoke purge or in emergency fire/
smoke situations to place priority on personnel protection.
Note: Smoke purge overrides all control inputs and bypass selector buttons. Smoke purge operation can only be terminated by opening the contact
u
Spare Multi-Function Digital Inputs
Terminals TB2-6 and TB2-7 are spare programmable inputs. The Bypass +24 V logic circuit is interconnected with the drive

4.5 Start-Up Procedure
Follow the steps and procedures outlined below to help ensure proper start-up of the P1000 Bypass.
u
Bypass Start-Up Preparation
Remove power to the P1000 Bypass and verify using a multimeter. Follow all appropriate lockout/tagout procedures.
1.
WARNING! Electrical Shock Hazard. Do not remove covers or touch circuit boards while the power is on. Failure to comply could
result in death or serious injury.
Record the motor nameplate information and verify that the input voltage matches the P1000 Bypass rating. Verify
2.
that the motor rated FLA does not exceed the rated output rating of the bypass unit, and verify that the motor FLA
falls in the rated range of the thermal overload relay (if present).
The P1000 Bypass provides an input circuit breaker. The adjustable trip level must be set using the two dials located
3.
on the circuit breaker. The dial marked “FLA” sets the breaker to match the motor FLA. Use a small straight-edge
screwdriver and adjust to the appropriate current level. The other dial sets the inrush level. Make sure this dial is set
to “Auto 1” (factory setting).
Verify that three-phase line power is connected to input circuit breaker.
4.
Verify that the grounding terminal of the P1000 Bypass is attached to the appropriate building ground circuit.
5.
Verify that wiring connections are properly terminated and connected to appropriate circuits at PCB A2 using the
6.
P1000 connection diagram. Refer to Standard Connection Diagram on page 42 for details.
Please note the following in regards to the safety circuit (DI-2, terminal TB2-2) and the BAS interlock circuit (DI-3,
terminal TB3-3):
Safety Interlock Circuit
DI-2 (terminal TB2-2) is provided to connect safety devices in a normally-closed series circuit, such as: freeze up
thermostats, smoke/fire sensors, high pressure limits, temperature limits, or vibration detectors.
The HOA keypad will display a Safety Open fault if a N.C. safety circuit is not closed between DI-2 (TB2-2) and IG24
(TB2-10) on PCB A2 at power-up with a Run command in HAND or AUTO mode. An open circuit between DI-2 (TB2-2)
and IG24 (TB2-10) will prevent bypass operation.
Take one of the following steps to ensure proper operation prior to startup:
Install a N.C. safety circuit between DI-2 (TB2-2) and IG24 (TB2-10) on PCB A2.
Install a jumper between DI-2 (TB2-2) and IG24 (TB2-10) on PCB A2.
Building Automation System Interlock Circuit (Drive and Bypass Enable Input)
The HOA keypad will display “INTRLOCK OPN” to indicate a BAS Interlock fault is a N.C. safety circuit is not closed
between DI-3 (TB2-3) and IG24 (TB2-10) on PCB A2 at power-up with a Run command in HAND or AUTO mode. An
open circuit between DI-3 (TB2-3) and IG24 (TB2-10) will prevent bypass operation.
This condition is a fault and will prevent drive and bypass operation.
Take one of the following steps to ensure proper operation prior to startup:
Install a N.C. BAS Interlock Circuit/Damper Interlock between DI-3 (TB2-3) and IG24 (TB2-10) on PCB A2.
Install a jumper between DI-3 (TB2-3) and IG24 (TB2-10) on PCB A2.
Verify that the motor is wired for the application voltage if it is a dual voltage motor.
7.
Connect the motor to the output terminals of the motor overload.
8.
Set the motor overload for the proper FLA of the motor.
9.
Verify that the motor ground is connected to the P1000 Bypass drive ground terminal.
10.
Record all other connections to the P1000 Bypass by terminal number to determine if special programming of any of
11.
the following is required:
Multi-function Digital Inputs – Bypass control board TB2 (A2)
Multi-function Digital Outputs – Bypass control board TB1 (A2)
Analog Inputs – Drive control board (A1)

Basic Auto-Tuning Preparations
n
• 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 at least equal to or greater than the motor rated voltage.
Note: Better performance is possible when using a motor with a base voltage that is lower than the input supply voltage (20 V for 208 V bypass
drive models and 40 V for 480 V bypass drive models). This is particularly important when operating the motor above 90% of base speed,
where high torque precision is required.
• To cancel Auto-Tuning, press the OFF key on the HOA keypad.
• When using a motor contactor, make sure it is closed throughout the Auto-Tuning process.

b3: Speed Search
The Speed Search function allows the drive to detect the speed of a rotating motor shaft that is driven by external forces and
start the motor operation directly from the detected speed without first stopping the machine.
YASKAWA SIEP YAIP1B 01A YASKAWA AC Drive – P1000 Bypass Technical Manual
85
5.2 b: Application
Example: When a momentary loss of power occurs, the drive output shuts off and the motor coasts. When power returns, the
drive can find the speed of the coasting motor and restart it directly.
For induction motors, the drive offers two types of Speed Search that can be selected by parameter b3-24 (Speed Estimation
and Current Detection). Both methods are explained below and followed by a description of all relevant parameters.
Current Detection Speed Search (b3-24 = 0)
n
Current Detection Speed Search detects the motor speed by looking at motor current in IM motors. When Speed Search is
started it reduces the output frequency starting from either the maximum output frequency or the frequency reference while
increasing the output voltage using the time set in parameter L2-04
<1>
. As long as the current is higher than the level set to
b3-02, the output frequency is lowered using the time constant set to b3-03. If the current falls below b3-02, the drive assumes
that the output frequency and motor speed are the same and accelerates or decelerates to the frequency reference.
<1> Details on this function can be found in the standard P1000 Technical Manual (SIEPYAIP1U01) at www.yaskawa.com.
Be aware that sudden acceleration may occur when using this method of Speed Search with relatively light loads.

When Speed Search is applied automatically with the Run command, the drive waits for the minimum baseblock time set to
L2-03 before starting Speed Search. If L2-03 is lower than the time set to parameter b3-05, then b3-05 is used as the wait time.

Notes on Using Current Detection Type Speed Search
• Shorten the Speed Search deceleration time set to b3-03 if an oL1 fault occurs while performing Current Detection Speed
Search.
• Increase the minimum baseblock time set to L2-03 if an overcurrent or overvoltage fault occurs when performing Speed
Search after power is restored following a momentary power loss.

Speed Estimation Type Speed Search (b3-24 = 1)
n
This method can be used for a single induction motor connected to a drive. Do not use this method if the motor is one or more
frame size smaller than the drive, at motor speeds above 200 Hz, or when using a single drive to operate more than one motor.
Speed Estimation is executed in the two steps described below:
Step 1: Back EMF Voltage Estimation
This method is used by Speed Search after baseblock (e.g., a power loss where the drive CPU continued to run and the Run
command was kept active). Here, the drive estimates the motor speed by analyzing the back EMF voltage and outputs the
estimated frequency and increases the voltage using the time constant set in parameter L2-04
<1>
. After that, the motor is
accelerated or decelerated to the frequency reference starting from the detected speed. If there is not enough residual voltage
in the motor windings to perform the calculations described above, the drive will automatically proceed to step 2.

Figure 5.9 Speed Search after Baseblock
<1> After AC power is restored, the drive will wait for at least the time set to b3-05. If the power interruption is longer than
the minimum baseblock time set to L2-03, the drive will wait until the time set to b3-05 has passed after power is restored
before starting Speed Search.
Step 2: Current Injection
Current Injection is performed when there is insufficient residual voltage in the motor after extended power losses, when Speed
Search is applied with the Run command (b3-01 = 1), or when an External search command is used.
This feature injects the amount of DC current set to b3-06 to the motor and detects the speed by measuring the current feedback.
The drive then outputs the detected frequency and increases the voltage using the time constant set to parameter L2-04
<1>
while looking at the motor current.
<1> Details on this function can be found in the standard P1000 Technical Manual (SIEPYAIP1U01) at www.yaskawa.com.
The output frequency is reduced if the current is higher than the level in b3-02. When the current falls below b3-02, the motor
speed is assumed to be found and the drive starts to accelerate or decelerate to the frequency reference.

Notes on Using Speed Estimation Speed Search
• Perform Rotational Auto-Tuning for V/f Control (T1-01 = 3) prior to using Speed Estimation in V/f Control and perform
Stationary Auto-Tuning for Line-to-Line Resistance (T1-01 = 2) again if the there is a change in the cable length between
the drive and motor.
• Use Current Detection to search for speeds beyond 200 Hz if the application is running multiple motors from the same drive
or if the motor is considerably smaller than the capacity of the drive.
• Speed Estimation may have trouble finding the actual speed if the motor cable is very long. Use Current Detection in these
instances.
• Use Current Detection instead of Speed Estimation when operating motors smaller than 1.5 kW because Speed Estimation
might not be able to detect the speed or rotation of these smaller motors, in which case Speed Estimation would stop the
motor.

When the number of maximum fault restarts in parameter L5-01 is set higher than 0, the drive will automatically perform
Speed Search as specified by b3-24 following a fault.
Method 4. After momentary power loss.
This mode requires that the Power Loss Ride-Thru function is enabled during CPU operation (L2-01 = 1 or 2). Refer to L2-01:
Momentary Power Loss Operation Selection on page 127.
Method 5. After external baseblock is released.
The drive will resume the operation starting with Speed Search if the Run command is present and the output frequency is
above the minimum frequency when the Baseblock command (H1-oo = 8 or 9) is released.

b5: PID Control
The drive has a built-in Proportional + Integral + Derivative (PID) controller that uses the difference between the target value
and the feedback value to adjust the drive output frequency to minimize deviation and provide accurate closed loop control
of system variables such as pressure or temperature.
P Control
n
The output of P control is the product of the deviation and the P gain so that it follows the deviation directly and linearly. With
P control, only an offset between the target and feedback remains.

5.2 b: Application
I Control
n
The output of I control is the integral of the deviation. It minimizes the offset between target and feedback value that typically
remains when pure P control is used. The integral time (I time) constant determines how fast the offset is eliminated.
D Control
n
D control predicts the deviation signal by multiplying its derivative (slope of the deviation) with a time constant, then adds
this value to the PID input. This way the D portion of a PID controller provides a braking action to the controller response and
can reduce the tendency to oscillate and overshoot.
D control tends to amplify noise on the deviation signal, which can result in control instability. Only use D control when
absolutely necessary.
PID Operation
n
To better demonstrate PID functionality, Figure 5.11 illustrates how the PID output changes when the PID input (deviation)
jumps from 0 to a constant level.

The PID setpoint input depends on the PID function setting in parameter b5-01.
If parameter b5-01 is set to 1 or 2, the frequency reference source in b1-01 (or b1-15) or one of the inputs listed in Table 5.3
becomes the PID setpoint.
If b5-01 is set to 3 or 4, then the PID setpoint can be input from one of the sources listed in Table 5.3.

PID Feedback Loss Detection
n
The PID feedback loss detection function detects broken sensors or broken sensor wiring. It should be used when PID control
is enabled to prevent critical machine conditions (e.g., acceleration to max. frequency) caused by a feedback loss.
Feedback loss can be detected in two ways:
• Feedback Low Detection
Detected when the feedback falls below a certain level for longer than the specified time. This function is set up using
parameters b5-12 to b5-14.
• Feedback High Detection
Detected when the feedback rises above a certain level for longer than the specified time. This function is set up using
parameters b5-12, b5-36, and b5-37.
The following figure illustrates the working principle of feedback loss detection when the feedback signal is too low. Feedback
high detection works in the same way.

Setting 0: Digital Output Only
A digital output set for “PID feedback low” (H2-oo = 3E) will be triggered if the PID feedback value is below the detection
level set to b5-13 for the time set to b5-14 or longer. A digital output set for “PID feedback high” (H2-oo = 3F) will be
triggered if the PID feedback value is beyond the detection level set to b5-36 for longer than the time set to b5-37. Neither a
fault nor an alarm is displayed on the digital operator and the drive will continue operation. The output resets when the feedback
value leaves the loss detection range.
Setting 1: Feedback Loss Alarm
If the PID feedback value falls below the level set to b5-13 for longer than the time set to b5-14, a “FBL - Feedback Low”
alarm will be displayed and a digital output set for “PID feedback low” (H2-oo = 3E) will be triggered. If the PID feedback
value exceeds the level set to b5-36 for longer than the time set to b5-37, a “FBH - Feedback High” alarm will be displayed
and a digital output set for “PID feedback high” (H2-oo = 3F) will be triggered. Both events trigger an alarm output
(H1-oo = 10). The drive will continue operation. The alarm and outputs reset when the feedback value leaves the loss detection
range.
Setting 2: Feedback Loss Fault
If the PID feedback value falls below the level set to b5-13 for longer than the time set to b5-14, a “FbL - Feedback Low”
fault will be displayed. If the PID feedback value exceeds the level set to b5-36 for longer than the time set to b5-37, a “FbH
- Feedback High” fault will be displayed. Both events trigger a fault output (H1-oo = E) and cause the drive to stop the
motor.
Setting 3: Digital Output Only, even if PID Is Disabled by Digital Input
Same as b5-12 = 0. Detection remains active when PID is disabled by a digital input (H1-oo = 19).
Setting 4: Feedback Loss Alarm, even if PID Is Disabled by Digital Input
