– The multi-function input terminals can be used to switch between
torque control and speed control. See parameter group E0 for rela‐
ted setting.
–
Speed control
–
Speed commands are used to control motor actions and
the speed controller is active.
– Output frequency changes according to set frequency
and the output torque changes with the load torque.
– The output torque is limited by ‘Torque limit’ [S1.02]. If
the load torque is larger than ‘Torque limit’ [S1.02], the
output frequency will be different from set frequency be‐
cause of torque limitation.
– Torque control
–
Speed controller is inactive and the output torque
changes according to the set torque.
– Output frequency changes with the load speed.
– The output speed is limited by ‘Upper frequency’ [b1.06].
If the load speed is larger than ‘Upper frequency’ [b1.06],
the output torque will be different from the set torque be‐
cause of speed limitation.
● 1: Always active
–
Torque control is always active.
Torque control is only active for ‘Control mode’ [b1.03] is ‘2: Field
oriented vector control (FOC)’.
S1.05
Torque control reference Factory default 0
Setting range 0, 1 Minimum unit 1
Used to select the source of reference torque in torque control mode.
●
0: TeI
–
The reference torque is set with the analog teI.
– The maximum value of +I input current corresponds to 200 % of
the rated torque.
– +I can only generate positive torque.
● 1: Terminal VR1
–
The reference torque is set with the analog terminal VR1.
– The maximum value of VR1 input voltage corresponds to 200 % of
the rated torque.
– VR1 can generate positive and negative torque. In this case, the
torque direction is determined by the polarity of the input voltage
regardless of settings of ‘Operating panel controlled direction’
[b1.08] and ‘Motor standard rotation direction’ [S3.14].
