10.8 Spindle logic outputs.
ENABLES (M5950) Main spindle
This signal is used when working with the spindle in closed loop (M19). The CNC only considers
the signals for the currently selected spindle.
The CNC sets this signal high to tell the PLC to allow the spindle to move.
DIRS (M5951) Main spindle
This signal is used when working with the spindle in closed loop (M19). The CNC only considers
the signals for the currently selected spindle.
The CNC uses this signal to tell the PLC in which direction the spindle is moving.
If the signal is at a high logic level, this indicates that the spindle moves in a negative direction.
If the signal is low, this indicates that the spindle moves in a positive direction.
REFPOINS (M5952) Main spindle
This signal is used when working with the spindle in closed loop (M19). The CNC only considers
the signals for the currently selected spindle.
The CNC sets this signal high to tell the PLC that the spindle reference point search has already
been made.
This is set low when the CNC is powered up, after executing the [SHIFT] [RESET] sequence or a
feedback alarm occurs due to loss of count, and every time a change is made from closed loop (M19)
to open loop.
DRSTAFS (M5953) | DRSTASS (M5954) Main spindle
The CNC uses these signals when communicating with the drive via CAN and they indicate the drive
status.
When an internal error occurs at the drive, the DRSTAF* and DRSTAS* signals are set low (logic
level low).
DRSTAF* DRSTAS*
Actuating the main switch of the electrical cabinet supplies
24 Vdc to the drive.
The drive runs an internal test.
If correct, it activates the output "System OK".
00
From that moment on, the power supply must be turned on.
When there is power at the drive bus, it is ready to output
torque.
01
To do that, activate the "drive enable" and "speed enable"
inputs.
10
Once the "drive enable" and "speed enable" are activated,
the drive is running properly.
