7.10 Holding Power of the Stitch Regulator Solenoid
Function with or without control panel
Time of full power
Holding Power of the Stitch Regulator Solenoid
Upper limit stitch regulator ON period
The stitch regulator solenoid is engaged by full power. Then the system switches automatically to partial power
in order to reduce the load for the control and the connected stitch regulator solenoid. Set the duration of full
power using parameter 212 and the partial holding power using parameter 213.
ATTENTION
If the holding power is set too high, the solenoid and the control may be permanently damaged.
Please observe the permissible duty ratio (ED) of the solenoid and set the appropriate value
according to the table below.
High holding power (full power)
7.11 Reverse motor rotation
Function with or without control panel
Positioning speed
Reversing angle
Switch-on delay of reverse motor rotation
Reverse motor rotation On/Off
The function "reverse motor rotation" is performed after trimming. When the stop position is reached, the drive
stops for the duration of the switch-on delay of reverse motor rotation. Then it runs in reverse direction at
positioning speed according to the set degrees.
