VD520
’s multi-function digital DI terminal, have two function associated with torque control: torque
control prohibit (function 40), speed control/torque control switch (function 39). The two terminals
should be use in conjunction with A0-00 to realize the switch between speed and torque control.
When the speed control/torque control switch terminal is invalid, the control mode is determined by
A0-00, if the speed control switch/torque control switch is effective, the control mode is equivalent to
the value of A0-00.
In any case, the frequency inverter is fixed to the speed control mode when the torque control prohibit
terminal is valid.

A0-01 is used to select the torque setting source, a total of 8 kinds of torque setting method.
Torque setting use the relative value, and 100% corresponding the rated torque of the inverter. Set
range -200.0%~200.0%, which shows that frequency inverter maximum torque of the 2 times the
rated torque of the inverter.
When the torque is setting using 1~7, communication, analog input, and 100% of pulse input
