Change of Operating Mode via Parallel Interface
To change the operating mode bits 8 and 9 of parameter P-0-4028,
Device control word have to be assigned to the digital inputs. By setting
the inputs, the bits for operating mode selection (primary mode of
operation and three secondary operating modes) are then set.
Main Spindle Drive with Analog Interface and Parallel
Interface
In the case of main spindle drives, operating states that are important for
the working cycle have to be transmitted to the master so that it can
process or advance the command blocks in accordance with the process
and in a fail-safe way.
The "position spindle" command allows aligning the spindle for tool
change without the control master having to leave the "velocity control"
mode mainly used for spindles.
In the case of master communication with analog interface, the required
messages have to be made available to the master via the digital outputs.
The "spindle positioning" command has to be started via a digital input.
To do this, the command parameters are assigned to a digital input, the
main spindle messages are assigned to the digital outputs.
The following commands are relevant for main spindle drives:
• C0900 Position spindle command (S-0-0152)
• C0600 Drive-controlled homing procedure command (S-0-0148)

The following messages are relevant for main spindle drives:
• speed reached (S-0-0330, Message 'n_actual = n_command')
• spindle has stopped (S-0-0331, Status 'n_feedback = 0')
• speed value has fallen below threshold (S-0-0332, Message 'nactual
< nx')
• in target position during spindle positioning
(S-0-0336, Message In position)
• torque limit value reached (S-0-0334, Message 'T >= Tlimit')
• torque threshold exceeded (S-0-0333, Message 'T >= Tx')
• speed threshold exceeded
(S-0-0335, Message 'n command > n limit')
• power threshold exceeded (S-0-0337, Message 'P >= Px')
