Operation
These parameters set limits on mechanical system movement.
The decimal point location is set by PP-01 (minimum setting unit).
When a software limit is detected, the motor is placed in servo-lock and stopped. The alarm output
status at that time is determined by the PP-25 (alarm selection) setting.
After the motor has been stopped as a result of a software limit having been detected, the motor will
only be able to be driven in the direction which will release it from the software limit. (If alarm A.L34 or
A.L35 has been generated, the alarm must be reset before the motor can be driven.)
If the maximum value is set for a given detection direction (e.g., 99,999,999 for the positive software
limit), then the software limit for that direction will be ignored and the alarm detection will not be acti-
vated.
PRM No. Parameter name
PP-14 Reference speed (leftmost
digits)
PRM No. Parameter name
PP-15 Reference speed (right-
most digits)
These parameters specify the motor's speed during positioning, as the amount of mechanical axis
movement per second.
The actual speed becomes the reference speed x the override. (The override value is set as PTP
speed data or by direct input.)
PRM No. Parameter name
PP-16 JOG speed
This parameter s
pecifies the motor r/min in JOG operation (+JOG, –JOG)
reference speed as 100%.
Note Set the JOG speed at or below the motor's maximum speed.
PRM No. Parameter name
PP-17 Origin search high speed
This parameter specifies origin proximity signal search speed in origin search operation as an over-
ride value based on the reference speed as 100%.
The origin search high speed is also used as the speed during origin compensation
Note Set an appropriate value so that the origin proximity signal can be detected accurately.
PRM No. Parameter name
PP-18 Origin search low speed
In origin search operation, this parameter specifies the motor sensor's Z-phase search speed after ori-
gin proximity signal detection as an override value based on the reference speed as 100%.
Note Set an appropriate value so that the speed will be 500 r/min maximum.
PRM No. Parameter name
PP-19 Origin search direction
