MDS-D-SVJ3/SPJ3 Series Instruction Manual
5-4 Spindle control signal
(2) Spindle control output 2
bit0. Z phase passed (ZCN)
[1] When Z phase is passed, ZCN=0 is turned to ZCN=1.
[2] Grid amount (within one rotation) is transmitted when ZCN =0 is changed to ZCN =1.
[3] When the zero point re-detection request (control input5/bitD) is changed from 0 to 1, ZCN=0 is
set.
bit3. In zero speed (ZS)
[1] Approximately 200ms after the motor speed reaches parameter SP027 (ZSP) + 15r/min, ZS=0
is set.
[2] When the motor speed becomes slower than the speed set by parameter SP027 (ZSP), ZS=1
is set. ZS signal is detected by the motor speed absolute value regardless of the rotation
direction.
bit7. In external emergency stop
It indicates that an external stop input to the drive unit is being input.
(Note) The bits other than those above are used for maintenance.
(3) Spindle control output 3
This is used for maintenance.
