Extension Setting Parameters ([Pr. Pc_ _ ]) - Mitsubishi Electric MR-J4-10B(-RJ) Instruction Manual

5. PARAMETERS

5.2.3 Extension setting parameters ([Pr. PC_ _ ])

No. Symbol
PC01 ERZ Error excessive alarm level
Set an error excessive alarm level.
Set this per rev. for rotary servo motors and direct drive motors. Setting "0" will be 3 rev.
Setting over 200 rev will be clamped with 200 rev.
Set this per mm for linear servo motors. Setting "0" will be 100 mm.
Note. Setting can be changed in [Pr. PC06].
PC02 MBR Electromagnetic brake sequence output
This is used to set the delay time between MBR (Electromagnetic brake interlock) and the
base drive circuit is shut-off.
PC03 *ENRS Encoder output pulse selection
This is used to select the encoder pulse direction and encoder output pulse setting.

Encoder output pulse phase selection
0: Increasing A-phase 90° in CCW or positive direction

Encoder output pulse setting selection
0: Output pulse setting
When "_ 1 0 _" is set to this parameter, [AL. 37 Parameter error]
will occur.
1: Division ratio setting
3: A-phase/B-phase pulse electronic gear setting
4: A/B-phase pulse through output setting
For linear servo motors, selecting "0" will output as division ratio
setting because the output pulse setting is not available.
Setting "4" will be enabled only when A/B/Z-phase differential
output linear encoder is used. And "Encoder output pulse phase
selection (_ _ _ x)" will be disabled. When another encoder is
connected, [AL. 37 Parameter error] will occur. Selecting "Standard
control mode (_ _ 0 _)" in [Pr. PA01 Operation mode] will trigger
[AL. 37 Parameter error].
Selection of the encoders for encoder output pulse
This is used for selecting an encoder for servo amplifier output.
0: Servo motor encoder
1: Load-side encoder
When "_ 1 0 _" is set to this parameter, [AL. 37 Parameter error]
will occur.
Selecting "1" in other than fully closed loop system or standard
control system (scale measurement function: enabled) triggers [AL.
37 Parameter error].
