(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.
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 power supply is being input.
bit9. In speed monitor
It indicates that a signal in speed monitor command is being received.
bitA. In door closed (controller)
It indicates that "In door closed" signal for controller is being received.
bitB. In door closed (self drive unit)
It indicates the status of "In door closed" signal for self drive unit.
(Note) The bits other than those above are used for maintenance.
