 d211: Homing reference signal, d212: Homing shift reference signal
The homing reference signal is used to switching from the homing frequency to the homing creep frequency. The
homing shift reference signal is used to start counting the homing shift. Normally, the home position LS is the homing
reference signal, and the Z-phase signal is the homing shift reference signal (factory default). If configuring homing
using other signals, select the homing reference signal and homing shift reference signal using the following table.
If other than Z-phase is selected for d212 homing shift reference signal, the configuration will have no homing
reference signal, and therefore the d211 homing reference signal will be invalid.
d211: Homing
reference signal
d212: Homing shift
reference signal

beginning homing shift
Enable
0: Z-phase
0: Z-phase (factory
default)
Creep frequency
Homing shift is started when the Z-phase is
detected for the first time after starting at the
creep frequency.

2: +OT
Homing frequency to

Decelerates to creep frequency when
performing reverse rotation when OT reached.
3: -OT

2: +OT
Homing frequency to
creep frequency
Decelerates to creep frequency when
performing reverse rotation when OT reached.
3: -OT
4: Stopper
Homing frequency to
creep frequency
A stopper collision is judged when torque
limiting occurs, the motor immediately moves
in the reverse rotation direction, and the
homing shift operation is performed at the
creep frequency.
 Position clear
Clears the current position to 0 when digital input “P-CLR” turns ON. Clearing is possible during position control or
speed control. The timing at which the position is cleared can be selected from the ON edge or ON level.

 Position preset
Rewrites the current position at the d240, d241 preset position at the digital input “P-PRESET” ON edge. Presetting
is possible during position control or speed control.
