Electromagnetic
brake closing delay
This parameter specifies the delay time of closing the electromagnetic brake. If the servo is off or
an alarm is reported in running state and the speed may be too fast, the digital output of the
electromagnetic brake release signal (0x005 or 0x105) becomes invalid after a period of delay. If
the motor speed drops below the setting of P3.58 during the delay period, the digital output
becomes invalid in advance.
Motor speed
threshold at brake
release
This parameter specifies the motor speed threshold when the brake is released.
This parameter specifies the condition for detecting torque reaching output. If the motor torque
feedback exceeds the setting of this parameter, the output of torque reaching (0x010 or 0x110) is
valid. The detection finds a lag of 5%.
This parameter specifies the voltage mode of the analog input dead zone.
CNC mode:
If the analog input is equal to or less than the dead zone, the
internal control value is 0.
If the analog input is greater than the dead zone, the internal
control value is (Analog input – Dead zone).
