Pn65 Undervoltage Alarm Selection
Setting range 0 or 1
Explanation of Settings
Setting
When the main power supply is interrupted during Servo ON status, a main power supply
0 undervoltage alarm (alarm code 13) does not occur and the Servo OFF status is entered.
When the main power supply turns ON again, the Servo ON status is reset.
When the main power supply is interrupted during Servo ON status, an error occurs for a
1
main power supply undervoltage (alarm code 13).
• Use this parameter to select whether to activate the main power supply undervoltage function
(alarm code 13) if the main power supply is interrupted for the Momentary Hold Time (Pn6D).
• If the Momentary Hold Time (Pn6D) is set to 1,000, Pn65 is disabled.
• If the setting of Momentary Hold Time (Pn6D) is too long and the voltage between P and N in the
main power supply converter drops below the specified value before a main power supply
interruption is detected, a main power supply undervoltage (alarm code 13) will occur regardless
of the setting of Pn65.
Pn66
Stop Selection for Drive Prohibition Input
Setting range 0 to 2
Explanation of Settings
Setting
During deceleration: The dynamic brake is activated. After stopping: The torque command
0
in the drive prohibit direction is set to 0. Deviation counter contents: Held
During deceleration: The torque command in the drive prohibit direction is set to 0. After
1 stopping: The torque command in the drive prohibit direction is set to 0. Deviation counter
contents: Held
During deceleration: An emergency stop is performed. After stopping: The servo is locked.
2
Deviation counter contents: Cleared before and after deceleration.
• Use this parameter to set the drive conditions during deceleration or after stopping after the
Forward Drive Prohibit Input (POT: CN1 pin 9) or Reverse Drive Prohibit Input (NOT: CN1 pin 8)
is enabled.
• If this parameter is set to 2, the Emergency Stop Torque (Pn6E) will be used to limit the torque
during deceleration.
• With a vertical axis, there is a risk that the load may drop when drive is prohibited by the drive
prohibit input. To prevent this, it is recommended that the deceleration method be set to use
emergency stop torque in the Drive Prohibit Input Stop Selection parameter (Pn066), and that
stopping in the servo-lock state be set (set value: 2).
• The dynamic brake is intended for emergency stop.
If the dynamic brake is activated, provide an interval of 3 minutes or more before the next
activation.
