MITSUBISHI CNC
5.7.2 Servo Control Output (Servo to NC)
(1) Servo control output 1
bit0. In ready ON (RDY)
It indicates that the status is in ready ON at RDN=1.
bit1. In servo ON (SRV)
It indicates that the drive unit turns ON (servo ON) at SRV=1.
bit4. In position loop gain changeover (KPM)
[1] The position loop gain (SV049/SV050/SV058) for spindle synchronous (synchronoustapping,
synchronous control with spindle C-axis, etc.) is being selected at KPM=1.
[2] The normal position loop gain (SV003/SV004/SV057) is being selected at KPM=0.
bit6. In excessive error detection width changeover (EOM)
[1] The excessive error width (SV053) for the special control (initial absolute position setting, stopper
control, etc.) is being selected at EOM =1.
[2] The normal excessive error width (SV023) is being selected at EOM =0.
bit7. In alarm (ALMR)
It indicates that drive unit is in some alarm state at ALM=1.
bit8. In current limit selection (IL1)
[1] The current (torque) limit (SV014) for the special control (initial absolute position setting,stopper
control, etc.) is being selected at IL1 =1.
[2] The normal current (torque) limit (SV013) is being selected at IL1 =0.
bitC. In in-position (INP)
The status changes to INP=1 when position droop exists within the in-position area set by parameter
SP024 (INP) regardless of serve ON or OFF.
bitD. In current limit (LMT)
It indicates that the drive unit is in current limit at LMT=1.
