■ MOTOR OFF
The motor control can be disabled by using the
MOTOR OFF command. After MOTOR OFF, the
drive axis can be moved freely, as long as there is
no motor brake. A monitoring of the actual position
will continue to take place, i.e. the actual position
(APOS) can still be queried after MOTOR OFF.
NB!
For a restart of a motion process after
MOTOR OFF the command MOTOR ON
must be used. Only the command ERRCLR auto-
matically activates MOTOR ON.

■ MOTOR ON
The motor control can be enabled again, following
a previous MOTOR OFF, by use of the MOTOR ON
command. When carrying out the MOTOR ON, the
commanded position is set to the actual position,
i.e. the motor remains at the actual position. Thus
the positioning error is reset at the execution of
MOTOR ON.
Summary
turns on motor control
Syntax
MOTOR ON
NB!
The MOTOR ON command is not suitable
for re-activation of position control following
an error. For this purpose, the ERRCLR command
is to be used.
