Part 1 Specification
z Current-limiting Value at Standstill after Missing Work Part in Push Operation (No. 91, PSFC)
This parameter defines the current-limiting value to be applied while the actuator is at standstill after missing the work in
push operation.
The definition varies between RACON and RPCON controllers as shown below.
RPCON
RACON Standstill mode = Power-saving
mode disabled
Standstill mode = Full-servo control
0
Current-limiting value during
movement (3 times the rated
motor current)
Current-limiting value at standstill in
positioning operation (Value of
parameter No .12)
Current-limiting value during
movement (3 times the rated motor
current)
1 Push-current limiting value Push-current limiting value Push-current limiting value
z Ball Screw Lead (No. 77, LEAD)
This parameter defines the ball screw lead.
Before shipment, this parameter has been set to a value appropriate for the characteristics of the actuator.
* Do not change the setting.
z Axis Operation Type (No. 78, ATYP)
This parameter sets whether the actuator is a linear operation axis or rotational operation axis.
0: Linear operation axis
1: Rotational operation axis
z Rotational Axis Mode Selection (No. 79, ATYP)
This parameter sets the rotational operation mode when the axis operation type is set to “rotational operation axis” (Parameter
No. 78 = 1).
0: Normal mode
1: Index mode
[Normal Mode]
Multi-rotational operation can be performed in a range of -9999.99 deg to 9999.99 deg.
[Index Mode]
Rotational operation can be performed in a range of 0 to 359.99 deg.
Caution
Push operation cannot be performed in the index mode. Even if push data is input in the position table, the data will be
ignored and the actuator will perform normal movement. The positioning band will conform to the setting of the default
positioning band parameter.
