User Constants
7.1.4 Sequence-related Constants
• Specifying a value other than 0 applies a secondary lag filter.
• Allowable setting range: 0 to 25000 U.i.s1
7.1.4 Sequence-related Constants
The following sequence-related user constants are available.
■ Cn-0012: Time Delay from Brake Reference to Servo OFF
• Sets the time delay from the brake reference output to Servo OFF when a Servomotor with
a brake is used.
• Allowable setting range: 0 to 50 [ x 10 ms]
Servo OFF
Servo ON
Brake Release
Drive ON
Brake Hold
Drive OFF
Cn-0012
■ Cn-0015: Brake Timing During Motor Running (Motor Speed for
Brake ON Reference)
• Sets the motor speed at which a brake reference is turned ON during servo OFF.
• If the motor speed is faster than this setting speed, the brake is releasing.
• Allowable setting range: 0 to maximum motor speed [r/min]
■ Cn-0016: Time Delay from Servo OFF to Forced Brake ON During
Motor Running
• Sets the time delay from Servo OFF until the brake ON.
• The mechanical brake is not immediately applied when the motor speed is faster than the
speed that was set to Cn-0015 after Servo is turned OFF. When the setting time has passed,
the brake hold regardless of the motor speed.
• Allowable setting range: 10 to 100 1x 10 ms]
