Setting Up the Drive 3-27
3.7 Macro 4
Torque control
Features
Specific features
Selection can be made between torque control and
frequency control.
When frequency control is selected, the Drive will
run at the frequency demand irrespective of load so
long as the maximum permissible output current of
the Drive is not reached. The frequency reference
must be applied to analog input 2.
When torque control is selected, analog input 1 is
configured for an analog torque reference. The
maximum frequency is limited to the value of
0.02 Maximum frequency. Analog input 2 is not used.
Both inputs accept 0 to 10V.
Torque slaving
Macro 4 can be used in applications where two or
more motors are mechanically linked and must share
the torque load in a controlled way.
