12.7.2 [P32: S_TM] Surge suppression at starts
When starting from the stopped state, the deviation is large, which increases the likelihood of surge
pressure. For this reason, pressure commands and flow rate commands are increased with a fixed
gradient to suppress the generation of surge pressure.
Display Code Parameter Name Setting range Default value Unit
P32 S_TM Surgeless start time 0.01 to 9.99 0.5 sec

Note that the gradient of the command value can be adjusted with “S_TM”, but that the gradient is subject
to restriction internally in the controller due to constraints on the response characteristics of the motor
control.
