5. Parameter Settings
z Home Check Sensor Input Polarity [No. 43 HMC]
Although standard actuators do not come with a home check sensor, this sensor can be installed as an option.
This parameter need not be changed in normal conditions of use. If the customer wishes to change the home check
mode after shipment, change the value set in Parameter No. 43.
Definition of settings: 0 (Standard specification; no sensor)
1 (Use the home check sensor, and the sensor polarity conforms to “contact a” logic)
2 (Use the home check sensor, and the sensor polarity conforms to “contact b” logic)
[Explanation of operation]
[1]
When a homing command is issued, the actuator moves until contacting the mechanical end, after which it
reverses the direction and stops at the home position.
[2] If a home check sensor signal has been detected by the time the actuator is stopped, the controller determines
that the homing was completed successfully. If a home check sensor signal is not detected before the actuator
stops, the controller recognizes “position deviation.” Accordingly, the controller generates a “home sensor not yet
detected” error and outputs an alarm signal.
z Home Sensor Input Polarity (No. 18 AIOF)
The input polarity of the home sensor is defined in Parameter No. 18.
Since the current RCA actuators do not adopt the home sensor mode, the factory setting is “0” [No sensor].
This parameter is provided to support future extension of actuator function. The customer is advised not to change the
setting.
Definition of settings: 0 (No sensor)
1 (Use the home sensor, and the sensor polarity conforms to “contact a” logic)
2 (Use the home sensor, and the sensor polarity conforms to “contact b” logic)
z Primary Filter Time Constant for Position Command (No. 55 PLPF)
Parameter No. Unit Input range Default
55 msec 0 ~ 100 0
This parameter sets the time constant to be applied when the primary filter for position command is enabled by the
acceleration/deceleration mode setting.
The setting unit for travel is “0.1” msec.
The greater the value set in this parameter, the longer the primary delay becomes.
* If “0” is set, acceleration and deceleration do not reflect any primary delay.
