6.5.3 Master-s lave
The motor controller CMMP-AS-...-M0 permits a master-slave operation, which is subsequently desig-
nated synchronisation. The motor controller can function both as master and as slave.
If the motor controller CMMP-AS -...-M0 operates as master, it can provide a slave with the c urrent rotor
position at the incremental encoder output [X11] .
If the motor controller CMMP-AS -...-M0 is to operate as slave, the [ X10] input is available for synchron-
isation. The motor controller CMMP-AS-...-M0 can calculate the speed pilot c ontrol itself. All inputs c an
be activated/deactivated. The int ernal encoder can be switched off optionally if another input is used
as the actual value encoder. This also applies in the speed adjustment operating mode.
The external inputs can be weighted with gear ratios. The various inputs c an be used individually and
also simultaneously.
6.5.4 Flying saw
“Flying saw” designates position-synchronous applications in which synchronisation is activated or
deactivated, dependent on the positioning record. The setpoint value at the synchronisation input is
added to the setpoint position value in the selected record only.
Prerequisites
The following settings must be parameterised:
1. Control int erface I/O or fieldbus
2. Selection of the following operating modes/functions
– Positioning mode
– Synchronisation ([ X10] /slave)
– Flying saw
3. Set the parameters of the encoder interface [X10].
Function
– Synchronous positioning records for synchronisation with the rotation of the master
– Non-synchronous positioning reco r ds for travel to the rest position/wait position
– Upward and downward synchronisation so that not jerking movements are generated.
