Chapter 7 Parameter
269
[42] Encoder voltage level (Parameter No.73)
No. Name Symbol Unit Input Range
Default factory
setting
73 Encoder Voltage Level EVLV - 0 to 3
Depending on
encoder cable
length
To stabilize encoder detection signals, this parameter defines the voltage supplied to the
encoder circuit to one of four levels in accordance with the encoder type and the length of the
encoder relay cable.
Normally this parameter need not be changed. If you have changed the length of the encoder
relay cable after the shipment, the value of the parameter may be changed.
If you wish to change this parameter, always consult us in advance. If the setting is not optimum,
it may cause an operation error of the actuator or malfunction of the encoder.
[43] Electromagnetic brake power monitor (Parameter No.75)
No. Name Symbol Unit Input Range
Default factory
setting
75 Electromagnetic Brake Power
Monitor
FSTP -
0: Disabled
1: Enabled
In accordance
with actuator
A power monitor function is provided to prevent actuator malfunction or breakdown of parts
caused by an abnormal voltage of the 24V brake power supply when an actuator with brake is
used.
Normally this parameter need not be changed because it has been set properly prior to the
shipment in accordance with the actuator, i.e. whether or not the actuator is equipped with
brake.
Set Value Description
0 Disabled (no brake)
1 Enabled (with brake)
[44] Belt breaking sensor input polarity (Parameter No.76)
This is the parameter for the future extension. Do not attempt to change the initial settings.
[45] Ball screw lead length (Parameter No.77)
No. Name Symbol Unit Input Range
Default factory
setting
77 Ball Screw Lead Length LEAD
mm
[deg]
0.01 to 999.99
In accordance
with actuator
This parameter set the ball screw lead length.
The factory setting is the value in accordance with the actuator characteristics.
 
Caution: If this parameter is set to “Disabled”, no brake control is provided.
 
Caution: If the setting is changed, not only the normal operation with indicated speed,
acceleration or amount to move is disabled, but also it may cause a
generation of alarm, or malfunction of the unit.
