SYNTAX    xOF, where x controller (axis) number.
PARAMETER none
DESCRIPTION This command is used to switch off the stepper motor current.
Note: when stepper motor becomes idle, after some delay the controller reduces motor current to low level (Iidle = 0.625 Imax) by default. The windings current keeps stepper motor at fixed position (holding current). If the current is switched off by xOF command (Iidle = 0), the precise position can be lost. The command may be used to switch off the stepper motor power if all jobs are done and exact stepper motor position is no more important. It saves power of (+24...36V) power supply which current drives the stepper motor.
RETURNS  none.
