Chapter 5. Parameters
P25
Displacement per revolution
Range
1 ~ 10000000
Unit
μm/rev
POWER
Definition
Designate a movement distance per revolution of a motor.
Description
Set the movement distance of a machine per revolution of a motor.
(Note) Set this parameter exactly. This parameter setting value is reflected on all
the positions and movement velocities.
P26
P gain
Range
1 ~ 1000
Unit
0.01/sec
RESET
Definition
Set the P gain of a position control loop.
The setting value‘100’is the optimal value.
This is valid during closed loop control of a pulse motor(MCU-MP2).
Description
‘100’is the optimal value as a P gain value of a position control loop.
For MCU-XP2 this is only valid when a position control loop is set. The position
control loop of MCU-XP2 can be selected by a parameter P68(In-position pulse).
Complete the tuning of a servo drive before setting this parameter.
P27
Motor rotation direction
Range
CW, CCW
Unit
POWER
Definition
Setting of the + rotation direction of a motor
CW: CW rotation as seen from the shaft side of a motor by the + command [0]
CCW: CCW rotation as seen from the shaft side of a motor by the + command [1]
Description
Set the + rotation direction of a motor.
If the movement direction of a machine is opposite during trial operation, then change
this parameter value.
P28
Following error
Range
0 ~ 1000000
Unit
μm
RESET
Definition
Setting of an allowable position deviation limit value
Description
Set the allowable position deviation limit value. If the setting value is‘1000000’,
then this function becomes invalid. If this function is valid, then the controller
generates an alarm and stops its operation when the difference between the absolute
position and the machine position is greater than or equal to the setting value.
The function of MCU-XP2 is applied based on the parameter P41(Reference pulses in
synchronization mode) setup value.
P29
Coordinate resetting range
Range
0 ~ 99999999
Unit
μm
RESET
Definition
Set an absolute position to reset a coordinate.
Description
If the absolute coordinate is greater than the setting value, then the
absolute coordinate and the machine coordinate roll over automatically.
If the setting value is‘0’, the function becomes invalid.
This function applies to the equipment moving infinitely in one direction.
(Note) Pay attention when applying this to reciprocating equipment.
