Pn52A (Multiplier per Fully-closed Rotation)
Set the coefficient of the deviation between the motor and the external encoder per motor rota-
tion.
This setting can be used to prevent the motor from running out of control due to damage to the
external encoder or to detect belt slippage.
Setting Example
Increase the value if the belt slips or is twisted excessively.
If this parameter is set to 0, the external encoder value will be read as it is.
If you use the default setting of 20, the second rotation will start with the deviation for the first
motor rotation multiplied by 0.8.
