Rate of Change Setting at Switching (Pn521 = 3)
If 3 is set in Torque Limit Selection (Pn521), you can add fluctuate the change at the time of
switching. This function is disabled in any other setting.
How to Set Rate of Change (Fluctuate)
Set the parameter according to the switching type.
From No. 1 torque limit to No. 2 torque limit: Pn523
From No. 2 torque limit to No. 1 torque limit: Pn524
The sign of the rate of change switches automatically inside the drive based on the magnitude
correlation of the No. 1 torque limit and No. 2 torque limit.
If the setting of No. 1 Torque Limit (Pn013) or No. 2 Torque Limit (Pn522) is changed from the
front panel or CX-Drive, the rate of change setting will be ignored and the new torque limit value
will be applied immediately.
Torque Limit Settings by Servomotors
The torque limit setting range is between 0% and 300%. The default setting is 300%. This is not
the case when a Servo Drive and a Servomotor are used in the following combinations.
