If limit switches are used for the homing, it must be ensured that the drive detects a limit switch
at the latest after a traverse path of
±2 31 -1 increments. Otherwise the homing must be started
again using a positive signal edge on the corresponding control signal.
Apart from the homing mode (C3213/000), the speed (C3242/000) for the homing and the ramp
times (C3252/000) for the homing can be set using further parameters.
Altogether the following parameters have an effect on the sequence of the homing:
Possible settings: Code
Default Selection
Comments
0: Zero pulse of the position feedback system
(MP) C0911 0
1: Touch probe input (TP, terminal E4)
Possible setting for the homing signal
0: >_Rn_MP/TP
1: <_Rn_MP/TP
8: >_MP/TP C3213 0
9: <_MP/TP
Definition of the homing mode:
Symbology:
> Movement in positive direction
< Movement in negative direction
Lp Positive limit switch
Ln Negative limit switch
Rp Positive edge on the homing switch
Rn Negative edge on the homing switch
MP/TP Zero pulse from the motor feedback system or
touch-probe edge on a digital input

[units]}
... 214748.0000 Home offset
C3242 100 1 {1[rpm]} ... 16000 Speed for the homing
C3252 5.00 0.01 {0.01[s]} ... 650.00 Ramp times for the homing:
These ramp times refer to C0011/000.
TIP!
In the parameterisable variant of the flying saw the homing switch is permanently linked to
digital input 3 on the servo PLC!
