PA1_26 Max. rotation speed (for torque control) is enabled only for VS type.
Enter the maximum rotation speed of the sevomotor for position, speed and torque control (VS type
only).
However, this parameter is disabled during pulse operation.
VS type: There is a difference of about 100 [r/min] between the reference value and actual
servomotor rotation speed under torque control when PA4_21 (torque control speed limit
selection) is set to 1 (older model compatibility).
In this case, use PA1_96 (speed limit gain for torque control) to adjust the error.
