Function
selection C-6 _ _ _ x [AL. 10 Undervoltage] detection method selection
Set this parameter when [AL. 10 Undervoltage] occurs due to distorted power supply
voltage waveform while using FR-RC-(H) or FR-CV-(H).
0: [AL. 10] not occurrence
1: [AL. 10] occurrence
This digit is not available with MR-J4-03A6-RJ servo amplifiers.
0h
_ _ x _ Main circuit power supply selection
Select a voltage to be connected to the main circuit power supply with an
MR-J4-03A6-RJ servo amplifier.
0: 48 V DC
1: 24 V DC
When using 24 V DC for the main circuit power supply, set "1" to this digit.
This digit is not available with MR-J4-_A_-RJ 100 W or more servo amplifiers.
The characteristics of the servo motor vary depending on whether 48 V DC or 24 V DC
is used. For details, refer to "Servo Motor Instruction Manual (Vol. 3)".
0h
_ x _ _ Undervoltage alarm selection
Select the alarm and warning that occurs when the bus voltage drops to the
undervoltage alarm level.
0: [AL. 10] regardless of servo motor speed
1: [AL. E9] at servo motor speed 50 r/min (50 mm/s) or less, [AL. 10] at over 50 r/min
(50 mm/s)

acceleration
time constant This parameter is used when a home position return is executed with the program
method. Set the acceleration time constant at the home position return. Set an
acceleration time from 0 r/min or 0 mm/s to the rated speed.
Additionally, when 20000 ms or more value is set, it will be clamped to 20000 ms.
Setting range: 0 to 50000 0

time constant
2 Set an second acceleration time constant for the automatic operation of the indexer
method.
Set an acceleration time from 0 r/min to the rated speed.
Additionally, when 20000 ms or more value is set, it will be clamped to 20000 ms.
Setting range: 0 to 50000 0

deceleration
time constant This parameter is used when a home position return is executed with the program
method. Set the deceleration time constant at the home position return. Set a
deceleration time from the rated speed to 0 r/min or 0 mm/s.
Additionally, when 20000 ms or more value is set, it will be clamped to 20000 ms.
Setting range: 0 to 50000 0
