- 139 -
JAC200 multifunctional digital DI terminal has two functions related with torque control: the torque control
prohibition (function 29) and speed control/ torque control switch (function 46). The two terminals shall be
used with A0-00 to switch between speed and torque control. The control mode is the opposite of A0-00
value.
Regardless of other factors, the frequency converter is fixed as speed control mode when the torque control
prohibition is efficient.

A0-01 is used for selecting torque setting source among which there are 8 setting modes.
Relative value is used by torque, corresponding to the related torque of motor and if the setting range is
-200.0%~200.0%, it displays that the maximum torque of frequency converter is 2 times of the related
torque of frequency converter.
When the torque reference is positive, the frequency converter is in forward running.
When the torque reference is negative, the frequency converter is in reverse running.
The description for the set source of every torque is displayed as follows:
0: digital setting (A0-03)
Target torque can use A0-03 set value directly.
