Print Registration
For both the Servo Driver axis 0 as the encoder input / output axis 1 the REG-
IST command can be used to perform print registration on the axis. Print reg-
istration captures an axis position as soon as a registration event occurs. The
registration event can be defined to be the moment when a registration input
or the Z-marker has been detected. Check the description of the REGIST
command for further details on print registration.
■
Print registration axis 0
Print registration on axis 0 is done by using the mechanism of the Servo
Driver. The registration can be triggered by either the Servomotor encoder Z-
marker or by the CN1-46 input of the Servo Driver. When the input is used,
one of the following settings is required.
■
Print registration axis 1
Print registration on axis 1 is done by using the MC Unit registration mecha-
nism. The registration can be triggered by either the input I0/R0, input I1/R1 or
the encoder input Z-marker of the MC Unit.
Two registration registers are provided for the axis. This allows for two simul-
taneous registration events for which the difference in positions can be deter-
mined.
Driver Limit Switches
The limit switches should be connected to the Servo Driver. In this case both
the Servo Driver and the MC Unit are able to put the system into a safe state.
In order to use the Driver POT and NOT signals also in the MC Unit, the fol-
lowing settings are required:
If one of the limits is reached, appropriate countermeasures will be performed.
See SECTION 8 Troubleshooting for details.
Output Mapping

MC Unit Digital Outputs
The physical outputs are freely allocable to any user defined functions. An
output can be set and reset depending on the current axis position by using
the command PSWITCH.
