1. Selecting speed/torque control mode (A0‑00)
Parameter A0‑00 determines whether the AC drive is in speed control or torque
control mode.
Multi‑functional DIs provide two torque control functions: torque control disabling
(function 29) and speed/torque control switchover (function 46). The two terminals
must be used together with parameter A0‑00 for switchover between speed control
and torque control.
When the speed control/torque control terminal (function 46 ) is disabled, the
control mode is determined by A0‑00. When the terminal is enabled, the control
mode is reverse to that set by A0‑00.
When the torque control disabling terminal is enabled, the AC drive works in speed
control mode.
2. Setting the torque reference in torque control (A0‑01, A0‑03)
A0‑01 is used to select a torque reference source from eight supported sources.
The torque reference is a relative value. The value 100.0% corresponds to the rated
motor torque. Check U0‑06 to obtain the motor output torque. The torque value
range is –200.0% to +200.0%, which means that the maximum torque of the AC
drive is twice the rated motor torque.
