Code and
Features
Description
Cn.53 Torque Lmt Src
Select a source for torque limit setting. Either keypad, analog inputs
(V1, V0 or I2) or communications. When setting torque limit, adjust
the torque amount by limiting the speed controller output. Set the
retrograde and regenerative limits for forward and reverse operation.
Configuration Function
0 KeyPad-1
Sets the torque limit with the keypad.
1 KeyPad-2
2
V1
Sets the torque limit with the V1 input terminal
of the terminal block.
4 V0
Sets the torque limit with the potentiometer
(volume dial) on the keypad.
5 I2
Sets the torque limit with the I2 input terminal of
the terminal block.
6 Int 485
Sets the torque limit with the communication
terminal of the terminal block.
8 FieldBus Sets the torque limit with the Fieldbus
communication option.
The torque limit can be set up to 200% of the rated motor torque.
Cn.54 FWD +Trq Lmt Sets the torque limit for forward retrograde (motoring) operation.
Cn.55 FWD
– Trq Lmt Sets the torque limit for forward regenerative operation.
Cn.56 REV -Trq Lmt Sets the torque limit for reverse regenerative operation.
Cn.57 REV +Trq Lmt Sets the torque limit for reverse retrograde (motoring) operation.
In.02 Torque at 100%
When using an analog input as the Torque Limit source (Cn.53), sets
the torque limit percentage at the maximum analog input.
For example, if V1 is used as the torque limit source and In.02 is set
to 200%, the torque limit is 200% at 10 V.
Gain value can be adjusted according to the load characteristics. However, use with
caution because motor overheating and system instability may occur depending on the
Gain value settings.
