Setting up Compax3 C3I22T11

Without positioning after homing run The position reached is not exactly on
0, as the drive brakes when detecting the home and stops:
If the homing mode is active, there will always be a homing run (see page 144)
with the first start after each configuration download (with the aid of the C3 Servo-
Manager).

or EnDat Multiturn absolute value sensor as feedback system, the
absolute position can be read in over the entire travel range when switching on the
Compax3. This means that a machine zero run is not necessary after the switchig
on (feedback may not be shifted by the absolute range while switched off).
In this case the reference only needs to be established once
at initial commissioning time
after an exchange of motor / feedback system
after a mechanical modification and
after an exchange of device (Compax3); does not apply for the "Store absolute
position in feedback" function.
after a configuration download
by carrying out a machine zero run.
The homing mode 35 "MN at the current position (see page 123)" is appropriate
for this, be
cause it is therewith possible to operate without proximity switch, but any
other homing mode is possible too - if the hardware prerequisites are fulfilled.
When you have once re-established the reference, reset the homing mode to
"without homing run".
