Make sure the protective earthing conductor complies with technical standards and local safety regulations.

Because the leakage current exceeds 3.5 mA, IEC/EN 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 crosssection of at least 10 mm2 (Cu) or 16 mm2 (Al) must be used. Failure to comply may result in death or serious injury.

Always use appropriate equipment for Ground Fault Circuit Interrupters (GFCIs).

The drive can cause a residual current with a DC component in the protective earthing conductor. Where a residual current operated protective or monitoring device is used for protection in case of direct or indirect contact, always use a type B GFCI according to IEC/EN 60755.

Fire Hazard

Do not use an improper voltage source.

Failure to comply could result in death or serious injury by fire. Verify that the rated voltage of the drive matches the voltage of the incoming power supply before applying power.

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.

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.

Enabling Speed Search for PM motors only requires setting parameter b3-01 to 1.

The drive offers current detection and speed estimation Speed Search for induction motors. Parameter b3-24 selects the speed search method for induction motors. Both methods and relevant parameters are explained below.

Current Detection Speed Search (b3-24 = 0)

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. 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 output 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.

Be aware that sudden acceleration may occur when using this method of Speed Search with relatively light loads.

Figure 1.10 illustrates Current Detection Speed Search operation after a momentary power loss (L2-01 must be set to 1 or 2):

Note: After power is restored, the drive waits until the time set to b3-05 has passed before performing Speed Search. Thereby the Speed Search

may start not at the end of L2-03 but even later.

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.

• Current Detection Speed Search is not available when using OLV Control for PM motors.

• 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)

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. 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 1.12 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 while looking at the motor current.

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.

Figure 1.13 Speed Search at Start

<1> The wait time for Speed Search (b3-05) determines the lower limit.

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.

• Use Short Circuit Braking instead of Speed Search when using OLV/PM with a long motor cable.

• Use Short Circuit Braking instead of Speed Search when attempting to find the speed of a motor coasting faster than 200

Hz in OLV/PM.

Speed Search Activation

Speed Search can be activated using any of the methods 1 through 5 described below. The Speed Search type must be selected in parameter b3-24 independent of the activation method.

Method 1. Automatically activate Speed Search with every Run command. External Speed Search commands are ignored.

Method 2. Activate Speed Search using the digital input terminals.

Use the input functions for H1-oo in Table 1.7.

Setting Description b3-24 = 0 b3-24 = 1

To activate Speed Search by a digital input, the input must be set together with the Run command or the Run command must be entered after giving the Speed Search command.

Method 3. After automatic fault restart.

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.

Timer Function Operation

Figure 1.14 Timer Operation

b5: PI Control

The drive has a built-in Proportional + Integral (PI) 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

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.

I Control

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.

PI Operation

To better demonstrate PI functionality, the diagram below illustrates how the PI output changes when the PI input (deviation) jumps from 0 to a constant level.

PI Feedback Loss Detection

The PI feedback loss detection function detects broken sensors or broken sensor wiring. It should be used when PI 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.

PI Sleep/Snooze

The PI Sleep/Snooze function stops the drive when the PI output or the frequency reference falls below the PID Sleep/Snooze operation level for a certain time. The drive will resume operating when the PI output or frequency reference rise above the PI Sleep/Snooze operation level for the specified time. An example of PI Sleep/Snooze operation appears in the figure below.

Parameter Details

Notes on Using the PI Sleep/Snooze Function

• The PI Sleep/Snooze function is active even when PI control is disabled.

• The PI Sleep/Snooze function stops the motor according to the stopping method set to b1-03. The PI Snooze Function is a variation on the Sleep Function. Set b5-21 to 2 to select the PI Snooze function. After selecting

the Snooze Function, the drive monitors the output frequency. If the output frequency drops below the PI Snooze Level (b5-22), and stays below that level for at least the time set to b5-23, PI Snooze Delay Time, the drive output shuts off.

YASKAWA SIEP YAIZ1U 03B YASKAWA AC Drive – Z1000 Programming Manual

Figure 1.18 PI Sleep/Snooze Operation

1.2 b: Application

The Snooze Function differs from the Sleep Function in that the feedback must drop below the level set to b5-24, PI Snooze Deactivation Level, before normal drive output will begin again. Immediately prior to Snooze Function activation, the PI Setpoint can be temporarily increased to create an overshoot of the intended PI Setpoint. The temporary boost is determined by parameter b5-25, PI Boost Setting Level.

After reaching the temporary boost level (or exceeding the time set to b5-26, PI Maximum Boost Time), the drive output shuts off (snoozes) and the intended PI Setpoint returns. From this point on, the Snooze Function operates normally and the drive output returns when the feedback level drops below b5-24.

The parameters necessary to control the PI Sleep/Snooze Function are explained below.

b5-15: PI Sleep Function Start Level

Sets the level that triggers PI Sleep/Snooze.

The drive goes into Sleep/Snooze mode if the PI output or frequency reference is smaller than b5-15 for longer than the time set to b5-16. The drive resumes operation when the PI output or frequency reference is above b5-15 for longer than the time set to b5-16.

b5-17: PI Accel/Decel Time

The PI acceleration/deceleration time is applied on the PI setpoint value. When the setpoint changes quickly, the normal C1-oo acceleration times reduce the responsiveness of the system as they

are applied after the PI output. The PI accel/decel time helps avoid the hunting and overshoot and undershoot that can result from the reduced responsiveness.

The PI acceleration/deceleration time can be canceled using a digital input programmed for “PI SFS cancel” (H1-oo = 34).

be set for “Ramp to stop” (b1-03 = 0).

Figure 1.19 Timing Diagram of Accel/Decel Time Change

Switching Accel/Decel Times by a Frequency Level

The drive can switch between different acceleration and deceleration times automatically. The drive will switch from accel/ decel time 2 in C1-03 and C1-04 to the default accel/decel time in C1-01 and C1-02 when the output frequency exceeds the frequency level set in parameter C1-11. When the frequency falls below this level, the accel/decel times are switched back.

Figure 1.20 shows an operation example.

Note: Acceleration and deceleration times selected by digital inputs have priority over the automatic switching by the frequency level set to C1-11.

For example, if accel/decel time 2 is selected, the drive will use only accel/decel time 2; it will not switch from accel/decel time 2 to the selected time.

C1-09: Fast Stop Time

Sets a special deceleration used when a select group of faults occur or when closing a digital input configured as H1-oo = 15 (N.O. input) or 17 (N.C. input). A momentary closure of the digital input will trigger the Fast Stop operation; it does not have to be closed continuously.

The drive cannot be restarted after initiating a Fast Stop operation until after completing deceleration, clearing the Fast Stop input, and cycling the Run command.

A digital output programmed for “During Fast Stop” (H2-oo = 4C) will be closed as long as Fast Stop is active.

NOTICE: Rapid deceleration can trigger an overvoltage fault. The drive output shuts off when faulted and the motor coasts. Set an appropriate Fast Stop time to C1-09 to avoid this uncontrolled motor state and to ensure that the motor stops quickly and safely.

C2: S-Curve Characteristics

Use S-curve characteristics to smooth acceleration and deceleration and minimize abrupt shock to the load. Set S-curve characteristic time during acceleration/deceleration at start and acceleration/deceleration at stop.

Torque Compensation in V/f and OLV/PM:

Determined by

A1-02

The drive calculates the motor primary voltage loss using the output current and the termination resistor value (E2-05 for IM motors, E5-05 for PM motors) and adjusts the output voltage to compensate insufficient torque at start or when load is applied. The effects of this voltage compensation can be increased or decreased using parameter C4-01.

Adjustment

Although this parameter rarely needs to be changed, it may be necessary to adjust the torque compensation gain in small steps of 0.05 in the following situations:

• Increase this setting when using a long motor cable.

• Decrease this setting when motor oscillation occurs. Adjust C4-01 so the output current does not exceed the drive rated current.

Note: Refrain from adjusting this parameter in OLV/PM. Setting this value too high can cause overcompensation and motor oscillation.

Note: 1. The following condition must be true when setting up the V/f pattern: E1-09 ≤ E1-07 < E1-06 ≤ E1-11 ≤ E1-04

2. To make the V/f pattern a straight line below E1-06, set E1-09 equal to E1-07. In this case the E1-08 setting is disregarded.

3. E1-03 is unaffected when the drive is initialized, but E1-04 through E1-13 return to their default values.

4. Only use E1-11, E1-12, and E1-13 to fine-tune the V/f pattern in the constant output range. These parameters rarely need to be changed.

Setting 0: 3-Wire Sequence

The digital input programmed for 3-Wire control becomes the forward/reverse directional input, S1 becomes the Run command input, and S2 becomes the Stop command input.

The drive starts the motor when the input S1 set for the Run command closes for longer than 2 ms. The drive stops the operation when the Stop input S2 is released. When the digital input programmed for a forward/reverse operation is open, the drive is set for forward operation. When the digital input is closed, the drive is set for reverse operation.

Note: Input the Run and Stop commands via S1 and S2 when selecting a 3-Wire sequence.

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

WARNING! Sudden Movement Hazard. The drive may start unexpectedly in reverse direction after power up if it is wired for 3-Wire sequence but set up for 2-Wire sequence (default). Make sure b1-17 is set to “0” (drive does not accept a Run command active at power up). When initializing the drive use 3-Wire initialization. Failure to comply could result in death or serious injury from moving equipment.

Settings 3 and 4: Multi-Step Speed Reference 1 and 2

Switches multi-step speed frequency references d1-01 to d1-04 by digital inputs. Refer to d1: Frequency Reference on page

Setting A: Accel/Decel Ramp Hold

When the digital input programmed for the Accel/decel ramp hold function closes, the drive locks (holds) the output frequency. Acceleration or deceleration resumes when the input is reopened.

If the Accel/decel ramp hold function is enabled (d4-01 = 1), the drive saves the output frequency to memory when the Ramp Hold input is closed. When the drive is restarted after stop or after power supply interruption, the saved output frequency becomes the frequency reference (provided that the Accel/decel ramp hold input is still closed). Refer to d4-01: Frequency

Reference Hold Function Selection on page 59 for details.

Setting B: Drive Overheat Alarm (oH2)

Triggers an oH2 alarm when the contact closes. Drive operation is not affected because this is an alarm.

Setting C: Analog Terminal Input Selection (Terminals A1 and A2)

When closed, the terminals specified in H3-14 are enabled. When open, the drive disregards the input signal to the analog terminals.

Setting F: Through Mode

Select this setting when using the terminal in a pass-through mode. When set to F, an input does not trigger any function in the drive. Setting F, however, still allows the input status to be read out by a PLC via a communication option or APOGEE FLN, BACnet, MEMOBUS/Modbus, or Metasys N2 communications.

1.7 H: Terminal Functions

Settings 10 and 11: Up/Down Function

The Up/Down function allows the frequency reference to be set by two push buttons when one digital input is programmed as the Up input (H1-oo= 10) to increase the frequency reference and the other digital input is programmed as the Down input (H1-oo= 11) to decrease the frequency reference.

The Up/Down function takes priority over the frequency references from the HOA keypad, the analog inputs, and the pulse input (b1-01 = 0, 1, 4). When using the Up/Down function, references provided by these sources will be disregarded.

The inputs operate as shown in the table below:

Status

Up (10) Down (11)

Open Open Hold current frequency reference

Closed Open Increase frequency reference

Open Closed Decrease frequency reference

Closed Closed Hold current frequency reference

Note: 1. An oPE03 alarm occurs when only one of the Up/Down functions is programmed to a digital input.

2. An oPE03 alarm occurs when the Up/Down function is assigned to the terminals and a different digital input is programmed for the

Accel/decel ramp hold function. Refer to the Troubleshooting chapter in the User Manual packaged with the drive for more information on alarms.

3. The Up/Down function can only be used for External reference 1. Consider this when using Up/Down and the external reference switching

command (H1-oo = 2).

Drive Operation

Using the Up/Down Function with Frequency Reference Hold (d4-01)

• If the frequency reference hold function is disabled (d4-01 = 0), the Up/Down frequency reference will be reset to 0 when the Run command is cleared or the power is cycled.

• When d4-01 = 1, the drive will save the frequency reference set by the Up/Down function. When the Run command or the power is cycled, the drive will restart with the saved reference value. Close the Up or Down input without an active Run command to reset the saved value. Refer to d4-01: Frequency Reference Hold Function Selection on page 59.

Using the Up/Down Function with Frequency Reference Limits

Parameter d2-01 determines the upper frequency reference limit.

The value for the lower frequency reference limit depends on the parameter d4-10 setting. This value can be set by an analog input or parameter d2-02. When a Run command is applied, the lower limits function as follows:

• If the lower limit is set by d2-02 only, the drive accelerates to this limit as soon as a Run command is entered.

• If the lower limit is determined by an analog input only, the drive accelerates to the limit when both the Run command and an Up or Down command are active. The drive will not start running if only the Run command is active.

• If the lower limit is set by both an analog input and d2-02, and the analog limit is higher than the d2-02 value, the drive accelerates to the d2-02 value when a Run command is input. When the d2-02 value is reached, the drive accelerates to the analog limit only if an Up or Down command is set.

Figure 1.33 shows an Up/Down function example with a lower frequency reference limit set by d2-02, and the frequency

reference hold function both enabled and disabled.

1.7 H: Terminal Functions

Settings 12 and 13: Forward Jog, Reverse Jog

Digital inputs programmed as Forward Jog (H1-oo = 12) and Reverse Jog (H1-oo = 13) will be Jog inputs that do not require a Run command. Closing the terminal set for Forward Jog input will cause the drive to ramp to the Jog frequency reference (d1-17) in the forward direction. The Reverse Jog will cause the same action in the reverse direction. The Forward Jog and Reverse Jog command can be set independently.

Note: The Forward Jog and Reverse Jog commands override all other frequency references. However, if the drive is set to prohibit reverse rotation

(b1-04 = 1), activating Reverse Jog will have no effect. Inputting the Forward Jog and Reverse Jog simultaneously for 500 ms or longer will trigger an alarm will and the drive will stop according to the stopping method set in b1-03..

Setting 14: Fault Reset

When the drive detects a fault condition, the fault output contact closes, the drive output shuts off, and the motor coasts to stop (specific stopping methods can be selected for some faults such as L1-04 for motor overheat). After removing the Run command, clear the fault either by pressing the RESET key on the HOA keypad or closing a digital input configured as a Fault Reset (H1-oo = 14).

Note: Remove the Run command prior to resetting a fault. Fault Reset commands are ignored while the Run command is present.

Settings 15 and 17: Fast Stop (N.O., N.C.)

The Fast Stop function operates similar to an emergency stop input to the drive. If a Fast Stop command is input while the drive is running, the drive decelerates to a stop in the deceleration time set to C1-09 (Refer to C1-09: Fast Stop Time on page

52). The drive can only be restarted after bringing the drive to a complete stop, turning off the Fast Stop input, and switching

off the Run command.

•

To trigger the Fast Stop function with an N.O. switch, set H1-oo = 15.

•

To trigger the Fast Stop function with an N.C. switch, set H1-oo = 17.

Setting 1B: Program Lockout

Parameter values cannot be changed when an input is programmed for Program Lockout and the input is open. It is still possible, however, to view and monitor parameter settings.

Setting 1E: Reference Sample Hold

This function allows the user to sample an analog frequency reference signal being input to terminal A1 or A2 and hold the frequency reference at the sampled level. When the Analog Frequency Reference Sample/Hold function is held for at least 100 ms, the drive reads the analog input and changes the frequency reference to the newly sampled speed as illustrated in

Figure 1.36.

When the power is shut off and the sampled analog frequency reference is cleared, the frequency reference is reset to 0.

Figure 1.36 Analog Frequency Reference Sample/Hold

An oPE03 error will occur when one of the following functions is used simultaneously with the Analog frequency reference sample/hold command:

• Hold accel/decel stop (Setting: A)

• Up command, Down command (Setting: 10, 11)

• Offset frequency (Setting: 44 to 46)

Setting 20 to 2F: External Fault

The External fault command stops the drive when problems occur with external devices.

To use the External fault command, set one of the multi-function digital inputs to a value between 20 and 2F. The HOA keypad will display EFo where o is the number of the terminal to which the external fault signal is assigned.

For example, if an external fault signal is input to terminal S3, “EF3” will be displayed. Select the value to be set in H1-oo from a combination of any of the following three conditions:

• Signal input level from peripheral devices (N.O., N.C.)

• External fault detection method

• Operation after external fault detection

The Customer Safeties multi-function input functionality is identical to Bypass Drive Enable (Setting 70: Drive Enable 2), except for the following:

• When the input is open, the stopping method is forced to Coast to Stop

• If the input is open when the Run command is present, a “SAFE” alarm is displayed instead of the “dnE” alarm.

Setting B2: BAS Interlock

The BAS Interlock multi-function input is used in a damper interlock circuit to keep the drive from running until the damper control relay is closed.

• When the input is open, the drive output is shut off (baseblocked).

• The drive will display an “inTLK” message if the input is open and a Run command is present. It will not display “dnE”.

• The state of the BAS Interlock multi-function input has no effect on the Emergency Override multi-function inputs

(H1-oo = AF, B0). The Emergency Override command will be accepted if the BAS Interlock digital input is open or closed.

1.7 H: Terminal Functions

Setting 0: Frequency Bias

The input value of an analog input set to this function will be added to the analog frequency reference value. When the frequency reference is supplied by a different source other than the analog inputs, this function will have no effect. Use this setting also when only one of the analog inputs is used to supply the frequency reference.

By default, analog inputs A1 and A2 are set for this function. Simultaneously using A1 and A2 increases the frequency reference by the total of all inputs.

Example: If the analog frequency reference from analog input terminal A1 is 50% and a bias of 20% is applied by analog input terminal A2, the resulting frequency reference will be 70% of the maximum output frequency.

Setting 1: Frequency Gain

The input value of an analog input set to this function will be multiplied with the analog frequency reference value.

Example: If the analog frequency reference from analog input terminal A1 is 80% and a gain of 50% is applied from analog input terminal A2, the resulting frequency reference will be 40% of the maximum output frequency.

Setting 2: Auxiliary Reference 1

Sets the auxiliary frequency reference 1 when multi-step speed operation is selected. Refer to Multi-Step Speed Selection on

page 56 for details.

Setting 3: Auxiliary Reference 2

Sets the auxiliary frequency reference 2 when multi-step speed operation is selected. Refer to Multi-Step Speed Selection on

page 56 for details.

Setting 4: Output Voltage Bias

Voltage bias boosts the output voltage of the V/f curve as a percentage of the maximum output voltage (E1-05). Available only when using V/f Control.

Setting 5: Accel/Decel Time Gain

Adjusts the gain level for the acceleration and deceleration times set to parameters C1-01 through C1-08. The drive acceleration time is calculated by multiplying the gain level to C1-oo as follows: C1-oo × Accel/decel time gain = Drive accel/decel time

Setting 7: Torque Detection Level

Using this setting, the overtorque/undertorque detection level for torque detection 1 (L6-01) can be set by an analog input. The analog input replaces the level set to L6-02. An analog input of 100% (10 V or 20 mA) sets a torque detection level equal to 100% drive rated current/motor rated torque. Adjust the analog input gain if higher detection level settings are required.

Refer to L6: Torque Detection on page 114 for details on torque detection.

Setting 8: Stall Prevention Level

Allows an analog input signal to adjust the Stall Prevention level. Figure 1.54 shows the setting characteristics. The drive will use the lower value of the Stall Prevention level set to L3-06 or the level coming from the selected analog input terminal.

The user can adjust the lower limit of the output frequency using an analog input signal.

Setting B: PI Feedback

Supplies the PI feedback value. This setting requires PI operation to be enabled in b5-01. Refer to PI Feedback Input

Methods on page 38.

Setting C: PI Setpoint

Supplies the PI setpoint value and makes the frequency reference selected in parameter b1-01 no longer the PI setpoint. PI operation to be enabled in b5-01 to use this setting. Refer to PI Setpoint Input Methods on page 37.

Setting D: Frequency Bias

The input value of an analog input set to this function will be added to the frequency reference. This function can be used with any frequency reference source.

Setting E: Motor Temperature

In addition to motor overload fault detection oL1, it is possible to use a PTC (Positive Temperature Coefficient) thermistor for motor insulation protection.

Setting F: Through Mode

When set to F, an input does not affect any drive function, but the input level can still be read out by a PLC via APOGEE FLN, BACnet, MEMOBUS/Modbus, or Metasys N2 communications.

Setting 16: Differential PI Feedback

If an analog value is set for this function, the PI controller is set for differential feedback. The difference of the PI feedback input value and the differential feedback input value builds the feedback value used to calculate the PI input. Refer to PI

Feedback Input Methods on page 38.

H4: Multi-Function Analog Outputs

These parameters assign functions to analog output terminals FM and AM for monitoring a specific aspect of drive performance.

H4-01, H4-04: Multi-Function Analog Output Terminal FM, AM Monitor Selection

H4-02, H4-03: Multi-Function Analog Output Terminal FM Gain and Bias

H4-05, H4-06: Multi-Function Analog Output Terminal AM Gain and Bias

Parameters H4-02 and H4-05 set the terminal FM and AM output signal level when the value of the selected monitor is at 100%. Parameters H4-03 and H4-06 set the terminal FM and AM output signal level when the value of the selected monitor is at 0%. Both are set as a percentage, where 100% equals 10 Vdc or 20 mA analog output and 0% equals 0 V or 4 mA. The output voltage of both terminals is limited to +/-10 Vdc.

The output signal range can be selected between 0 to +10 Vdc or -10 to +10 Vdc, or 4 to 20 mA using parameter H4-07 and H4-08. Figure 1.55 illustrates how gain and bias settings work.

Using Gain and Bias to Adjust Output Signal Level

When viewing a gain setting parameter (H4-02 or H4-05) on the HOA keypad, the analog output will supply a voltage signal equal to 100% of the monitor value (including changes made from bias and gain settings). When viewing a bias setting parameter (H4-03 or H4-06), the analog output voltage will supply a signal equal to 0% monitor value.

Example 1: Set H4-02 to 50% for an output signal of 5 V at terminal FM when the monitored value is at 100%.

Example 2: Set H4-02 to 150% for an output signal of 10 V at terminal FM when the monitored value is at 76.7%.

1.8 L: Protection Functions

L1: Motor Protection

L1-01: Motor Overload Protection Selection

The drive has an electronic overload protection function that estimates the motor overload level based on output current, output frequency, thermal motor characteristics, and time. When the drive detects a motor overload an oL1 fault is triggered and the drive output shuts off.

L1-01 sets the overload protection function characteristics according to the motor being used.

A1-02

Note: 1. When the motor protection function is enabled (L1-01≠ 0), an oL1 alarm can be output through one of the multi-function outputs by

setting H2-01 to 1F. The output closes when the motor overload level reaches 90% of the oL1 detection level.

2. Set L1-01 to a value between 1 and 5 when running a single motor from the drive to select a method to protect the motor from overheat. An external thermal relay is not necessary.

Setting 0: Disabled (Motor Overload Protection Is not Provided)

Use this setting if no motor overheat protection is desired or if multiple motors are connected to a single drive. If multiple motors are connected to a single drive, install a thermal relay for each motor as shown in Figure 1.57.

Figure 1.57 Example of Protection Circuit Design for Multiple Motors

NOTICE: Thermal protection cannot be provided when running multi-motors simultaneously with the same drive, or when using motors with

a relatively high current rating compared to other standard motors (such as a submersible motor). Failure to comply could result in motor damage. Disable the electronic overload protection of the drive (L1-01 = “0: Disabled”) and protect each motor with individual motor thermal overloads.

Setting 1: General-Purpose Motor (Standard Self-Cooled)

Because the motor is self-cooled, the maximum load current drops when the motor speed is lowered. The drive appropriately adjusts the electrothermal trigger point according to the motor overload characteristics, protecting the motor from overheat throughout the entire speed range.

Motor designed to operate from line power. Motor cooling is most effective when running at rated base frequency (check the motor nameplate or specifications).

Continuous operation at less than line power frequency with 100% load can trigger motor overload protection (oL1). A fault is output and the motor will coast to stop.

Use this setting when operating a PM motor. PM motors for derated torque have a self-cooling design and the maximum load current drops as the motor slows. Electronic thermal overload is triggered in accordance with the motor overload characteristics, providing overheat protection across the entire speed range.

Figure 1.58 illustrates an example of the electrothermal protection operation time using a general-purpose motor operating at

the value of E1-06, Motor Base Speed, with L1-02 set to one minute.

During normal operation, motor overload protection operates in the area between a cold start and a hot start.

• Cold start: Motor protection operation time in response to an overload situation that was suddenly reached when starting a stationary motor.

• Hot start: Motor protection operation time in response to an overload situation that occurred during sustained operation at rated current.

Motor Protection Using a Positive Temperature Coefficient (PTC) Thermistor

Connect a motor PTC to an analog input of the drive for motor overheat protection.

When the PTC input signal reaches the motor overheat alarm level, an oH3 alarm will be triggered and the drive will continue operation as selected in L1-03. When the PTC input signal reaches the overheat fault level, an oH4 fault will be triggered, a fault signal will be output, and the drive will stop the motor using the stopping method determined in L1-04.

Figure 1.59 shows a PTC connection example for analog input A2. When using analog input A2, be sure to set Jumper S1 on

the control board for voltage input when using this function.
