5-9-4 Torque limiter function
(1) Torque limit setting selection
The torque limit can be set independently for both speed control (ASR mode) or torque control (ACR
mode) independently for drive or regeneration status. If the VAT2000 is stopped by the emergency
stop signal (EMS), then the regeneration limit is fixed by parameter A10-5.
The parameters used in the torque limiter function are shown below..
A10-3 : ASR drive torque limit setting
A10-4 : ASR regenerative torque limit setting
A10-5 : Emergency stop regenerative torque limit setting
A11-2 : ACR drive torque limit setting
A11-3 : ACR regenerative torque limit setting
The value of above limits can be reduced by external settings. The final limit value results multiplying
the above selected limit with the reduction ratio.
