Parameters A - 18

E4-08

<3021>

Motor 2 Slip

Compensation Gain

SlpCmp Gain Mtr2

This parameter can help to increase speed precision when working

on a load, although normally adjustment is not necessary.

• When speed is less than that desired value, increase the set value.

• When speed is higher than the desired value, decrease the set

value.

* This parameter functions as gain suppression when in Flux Vector

Control.

Motor 2 Torque

Compensation Gain

TrqCmp Gain Mtr2

Magnifies the torque compensation gain. Normally this parameter

does not require change, however, adjustments can be made as fol-

lows:

• When the motor cable is long, increase the setting.

• When using a motor with a smaller capacity than the drive (the

largest motor being used), increase this setting.

• If the motor begins to vibrate, adjust the value set so that the

output current does not exceed the drive’s rated output current

when operating at low speeds.

Overspeed (OS)

PG Overspeed Sel

Sets the stopping method when an overspeed (OS) fault occurs. See

F1-08 and F1-09.

PG Deviation Sel

Sets the stopping method when a speed deviation (DEV) fault

occurs. See F1-10 and F1-11.

0: Ramp to stop - Decelerate to stop using the active deceleration

time.

F1-06

PG Division Rate (PG Pulse

Monitor)

PG Output Ratio

Sets the division ratio for the pulse monitor of the PG-B2 encoder

feedback option board. This function is not available with the

PG-X2 option board.

Division ratio = (1+ n) /m (n=0 to 1, m=1 to 32)

The first digit of the value of F1-06 stands for n, the second and the

third stand for m. (from left to right).

The possible division ratio settings are:

1/32 ≤ F1-06 ≤ 1

1 to 132 1 - A - A

Denotes that parameter can be changed when the Drive is running. For Normal Duty (ND) Rating: Setting Range=40.0 to 400.0.

* For Heavy Duty (HD) Rating: Setting Range=40.0 to 300.0.

*1: Default setting changes according to the control mode (E3-01). When E3-01 = 0, E4-08 = 0.0. When E3-01 = 2 or 3, E4-08 = 1.0.

*2: Setting range becomes 1.00 to 300.00 in Flux Vector Control

*3: Default setting changes according to the control mode (E3-01) When E3-01 = 1, E4-09 = 0.20 and E4-10 = 0.200. When E3-01 = 3, E4-09 = 20.00 and E4-10 = 0.500.
