• When the control output type is R1 (motor drive relay output), the display and setting
can be performed. However, if [
C59
: Motor long life mode] is set at “1” (aiming at
the service life of the potentiometer), the display and setting cannot be performed.
The dead zone between the motor open and motor close in the position
proportional control is set.
For setting reference, this dead zone is changed when the manual output is output
at a constant rate. The value, which is obtained when the hunting of the motor is
stopped, is the minimum value of the dead zone.
If the exactly minimum value is set, the motor is always moved, causing the
service life of the motor to be shortened extremely.
The default setting before shipment is “10.0%”. With this default value used as
reference value, the setting is made correctly by taking the control results and
service life of the motor into consideration.
