r For reference setting, select the homing mode "100" in C02640 .
r The homing modes "0"..."15", which are described in detail in the following sections, are
available for a reference search in C02640 .
– Depending on the mode selected the following switches/sensors are evaluated:
Switch Input for digital input signal
Reference switch HM_bHomingMark on SB LS_Homing
Touch probe sensor DIGIN_bIn1 ... DIGIN_bIn8 (or optional use of the motor encoder or load
encoder zero pulse). Configuration: C02651 .
Positive travel range limit switch LIM_bLimitSwitchPositive on SB LS_Limiter
Negative travel range limit switch LIM_bLimitSwitchNegative on SB LS_Limiter
Note!
In the homing modes 0...5 as well as 10 and 11, the search for the limit switch/
reference switch is achieved by changing over to a higher speed than for
approaching the encoder zero pulse/touch probe sensor. This serves to reduce
the homing time and increase the accuracy.
After setting the home position the drive travels to the target position set in
C02643 .
Operation of mode 0:
1. Movement in positive direction.
2. Negative edge at HM_bHomingMark enables
home position detection.
3. The following positive edge of the encoder
zero pulse/touch probe sensor set the
reference.
Operation of mode 1:
1. Movement in negative direction.
2. Negative edge at HM_bHomingMark enables
home position detection.
3. The following positive edge of the encoder
zero pulse/touch probe sensor set the
reference.
