Programmable SyncPos motion controller
41 HOME_RAMP
Acceleration to be used during movement to home
position. This statement refers to the minimum ramp,
which is defined under the RAMPMIN (31) parame-
ter. This unit results from the parameter VELRES (22)
usually in % of the minimal ramp; 50% means half
as fast, i.e. twice as long.
The following cohesion for HOME_RAMP results:
HOME_RAMP [ms] =
VELRES (22)
HOME_RAMP (41)
· RAMPMIN (31) [ms]

NB!
HOME_RAMP can never have a higher value
than DFLTACC (34).
42 HOME_OFFSET
HOME_OFFSET is used to introduce an offset
compared to the reference switch or index pulse.
After homing, the drive is positioned to
HOME_OFFSET. At this point the zero point is set.

43 ERRCOND
ERRCOND determines the behavior in event of an
error as follows:
0 = Standard, i.e. drive moves in COASTING, control
loop is interrupted.
1 = like 0, but brake is activated,
see O_BRAKE (48)
2 = motor stop with max. deceleration (stop ramp),
subsequently standstill control
3 = like 2, brake is activated in addition, but only
after MOTOR STOP.
All other activities such as MOTOR OFF etc.
must be set in the ON_ERROR routine.

reached.
