setting
33 Torque Filter Time Constant TRQF – 0 to 2500
In accordance with
actuator
This parameter decides the filter time constant for the torque command. When vibrations
and/or noises occur due to mechanical resonance during operation, this parameter may be
able to suppress the mechanical resonance. This function is effective for torsion resonance of
ball screws (several hundreds Hz).
[26] Press Velocity (Parameter No.34)
No. Name Symbol Unit Input Range

(deg/s)
1 to actuator's max.
pressing speed
In accordance with
actuator
This is the parameter to set the velocity in pressing operation.
The setting is done considering the actuator type when the product is delivered.
[Refer to 10.5 List of Specifications of Connectable Actuators]
If a change to the setting is required, make sure to have the setting below the maximum
pressing velocity of the actuator. Setting it fast may disable to obtain the specified pressing
force. Also when setting at a low velocity, take 5mm/s as the minimum.

Positioning Velocity
Caution: If the velocity of the positioning of the position table is set below this
parameter, the pressing speed will become the same as the positioning
speed.
[27] Safety Velocity (Parameter No.35)
No. Name Symbol Unit Input Range
Default factory
setting
35 Safety Velocity SAFV
mm/s

1 to 250 (maximum
speed for the
actuators with 250 or
less)

This is the parameter to set the maximum speed of manual operation while the safety velocity
selected in the teaching tool. Do not have the setting more than necessary.
