4.4.2 Parameters Relating to Actuator Stroke
z Soft Limits (Nos. 3/4, LIMM/LIML)
Set the + soft limit in parameter No. 3 and – soft limit in parameter No. 4.
Both parameters have been set to the effective actuator length at the factory. Change the parameter settings if necessary,
such as when an obstacle is present and collision between the actuator and obstacle must be prevented.
Exercise due caution when setting these parameters, as wrong settings will cause collision with the mechanical end.
The minimum setting unit is 0.01 mm.
Caution
To change these parameters, set values corresponding to positions that are 0.3 mm wider than the desired effective range.
Example) Set the effective range to between 0 and 80 mm
Parameter No. 3 (+): 80.3
Parameter No. 4 (–): -0.3
z Home Return Direction (No. 5, ORG)
If not specified by the customer, the home return direction is set to the motor side before shipment.
If you must change the home direction after the actuator has been assembled to your equipment, change the setting of
parameter No. 5.
Also change the parameters for home return offset and soft limits, if necessary.
Caution
Even after the home return direction is reversed, stored position data will be retained.
Rod-type actuators must be used with its home on the motor side. (Do not reverse the factory-set home return direction.)
