Pn6C Regeneration Resistor Selection
Setting range 0 to 3
Explanation of Settings
Setting
Regeneration resistor used: Built-in resistor
0 The regeneration processing circuit will operate and the regeneration overload (alarm code
18) will operate according to the internal resistor (with approximately 1% duty).
Regeneration resistor used: External resistor
1 The regeneration processing circuit will operate, and regeneration overload (alarm code 18)
will cause a trip when the operating rate of the regeneration resistor exceeds 10%.
Regeneration resistor used: External resistor
2 The regeneration processing circuit will operate, but regeneration overload (alarm code 18)
will not.
Regeneration resistor used: None
3 The regeneration processing circuit and regeneration overload (alarm code 18) will not
operate, and all regenerative energy will be processed by the built-in capacitor.
• Do not touch the External Regeneration Resistor. It can be very hot and may cause burns.
• Always provide a temperature fuse or other protective measure when using an External
Regeneration Resistor. Regardless of whether the regeneration overload is enabled or disabled,
the External Regeneration Resistor can become extremely hot and may cause burning.
• Set this parameter depending on whether the built-in regeneration resistor is used, or the built-in
regeneration resistor is disconnected and an External Regeneration Resistor is connected. (The
External Regeneration Resistor is connected between B1 and B2.)
• To use the built-in regeneration resistor, always set this parameter to 0.
Pn6D Momentary Hold Time
Setting range 35 to 1000
• Use this parameter to set the amount of time required until shutoff is detected if the main power
supply remains shut off.
• The main power OFF detection will be disabled if this parameter is set to 1000.
Pn6E
Emergency Stop Torque
Setting range 0 to 500
• Use this parameter to set the torque limit for the following cases.
• Drive prohibit deceleration with the Stop Selection for Drive Prohibition Input (Pn66) set to 2.
• Deceleration with the Stop Selection with Main Power OFF (Pn67) set to 8 or 9.
• Deceleration with the Stop Selection with Servo OFF (Pn69) set to 8 or 9.
• The normal torque limit will be used if this parameter is set to 0.
Pn70 Deviation Counter Overflow Level
Setting range 0 to 32767
• Use this parameter to set the deviation counter overflow level.
• The set value is calculated using the following formula.
Set value = Deviation counter overflow detection pulses [pulses]/256
