Chapter 8 Applied Functions
CON-48 ACR P-Gain, CON-49 ACR I Gain : Used in sensorless speed/torque and vector speed/torque modes and
adjusts the P gain and I gain of the current PI controller.
IN-65~75 Px Define
36 : ASR Gain2
If the set terminal is input, the gain can be changed after the change time(CON-19).
37 : ASR P/PI
Moves during stop. If the set terminal is input, the integral controller is not active.
6) Torque Limit
The size of the torque reference is adjusted by limiting the speed controller output. As in the following figure, both reverse
and regenerative limits for forward and reverse operation can be set.
CON-53 Torque Lmt Src : Selects the type of torque limit setting. The torque limit can be set by using the keypad, analog
input of the terminal block(V1, I1) or communication option.
0 : Keypad-1, 1 : Keypad-2
Sets the torque limit using the keypad. Up to 200% can be set on the basis of the rated torque of the motor and the limits
on the rotation direction, reverse and regenerative limits are set in the following codes.
CON-33 FWD +Trq Lmt : forward motoring operation torque limit
CON-34 FWD –Trq Lmt : forward regeneration operation torque limit
CON-35 REV +Trq Lmt : reverse motoring operation torque limit
CON-36 REV –Trq Lmt : reverse regeneration operation torque limit
2 : V1, 3 : I1
The torque limit is set by using the analog input terminal of the inverter terminal block. The maximum torque is set by using
IN-02 Torque at 100% item. For example, if IN-02 is set at 200% and voltage input(V1) is used, the torque limit is 200%
when 10V is input(only when the V1 terminal function is set at the default function). When the torque limit setting method is
other than the keypad, the set value is confirmed in the monitor mode. No. 20 Torque Limit is selected in Config Mode
CNF-06~08.
3 : Int 485
Sets the torque limit using the communication terminal of the inverter terminal block.
Torque Bias Setting
CON-58 Trq Bias Src : Selects the type of setting of the offset value added to the torque reference.
0 : Keypad-1, 1 : Keypad-2
Setting by using the keypad is input in CON-38 Torque Bias. up to 120% of the rated current of the motor can be set.
2 : V1, 3 : I1, 6 : Int 485
The setting method is the same as the torque reference described above. The setting can be checked in MON mode and
select No. 21 Torque Bias among CNF-06 ~ 08.
