Analog speed
command
offset/
Analog speed
limit offset Set the offset voltage of VC (Analog speed command).
For example, if CCW rotation or positive direction travel is provided by switching on
ST1 (Forward rotation start) while applying 0 V to VC, set a negative value.
When automatic VC offset is used, the automatically offset value is set to this
parameter. (Refer to section 4.5.4.)
The initial value is provided before shipment by the automatic VC offset function on
condition that the voltage between VC and LG is 0 V.
Setting range: -9999 to 9999
The value
differs
depending
on the
servo
amplifiers.
[mV]
Set the offset voltage of VLA (Analog speed limit).
For example, if CCW rotation or positive direction travel is provided by switching on
RS1 (Forward rotation selection) while applying 0 V to VLA, set a negative value.
When automatic VC offset is used, the automatically offset value is set to this
parameter. (Refer to section 4.5.4.)
The initial value is provided before shipment by the automatic VC offset function on
condition that the voltage between VLA and LG is 0 V.
Setting range: -9999 to 9999

ERZ
Error
excessive
alarm level Set an error excessive alarm level.
You can change the setting unit with "Error excessive alarm/error excessive warning
level unit selection" in [Pr. PC24].
Set this per rev. for rotary servo motors and direct drive motors. Setting "0" will be "3
rev", and setting over 200 rev will be clamped with 200 rev. Set this per mm for
linear servo motors. Setting "0" will be 100 mm.
Setting range: 0 to 1000 0

x _ _ _ Load-side encoder cable communication method selection
Select the communication method of the encoder cable to be connected to the CN2L
connector of MR-J4-_A_-RJ.
0: Two-wire type
1: Four-wire type
When using a load-side encoder of A/B/Z-phase differential output method, set "0".
Incorrect setting will trigger [AL. 70] and [AL. 71]. Setting "1" while using a servo
amplifier other than MR-J4-_A_-RJ will trigger [AL. 37].
This digit is not available with MR-J4-03A6 servo amplifiers.
