Set the acceleration at homing.
An appropriate value corresponding to the applicable actuator has been set at shipment from the factory.
 Calculation formula of the setting value (pulse/sec
2
) of acceleration (mm/sec
2
)
The setting value of the acceleration is converted from mm/sec
2
to pulse/sec

z The setting value of this item indicates pulses of the encoder, and is independent of the electronic
gear setting. The number of pulses of the encoder varies depending on the type of actuator. See (8),
“Number of Encoder Pulses.”

Offset amount at homing OFST pulse 1~134217727 [A]
Set the amount of movement from the position at which phase Z is detected after reversing at the
mechanical end in a push operation, for the homing operation.
An appropriate value corresponding to the applicable actuator has been set at shipment from the factory.
