POWER OK
Information to the control system from the common logic for external axes. If this signal is
not used for external axes, it must be jumpered.

PTCM7.0VPTCM7
Temperature monitoring of a motor. The motor's PTC-resistor is connected in a closed loop.
Open loop indicates that the motor temperature is too high. If a temperature monitor is not
used, the circuit must be jumpered.

Power supply
+24VI/O,0V
An internal 24 V voltage from the control cabinet Provided the permissible load is not
exceeded, the voltage can be used for the following:
• Supply of sync, switches and associated control function (external axes without
absolute measurement).
• Supply of external brakes.
X FINE (7-12), Y FINE (7-12), X COARSE (7-12), Y COARSE (7-12), O V
The X FINE, Y FINE and 0 V signals are used for connecting fine resolvers to the control
system.
The X COARSE, Y COARSE and 0 V signals are used for connecting coarse resolvers
the external axes are provided with absolute measurement.
when
X COARSE can also be used to connect sync, switches supplied by the EXC, (see below), if the
level of disturbance is moderate. However, in environments with a high level of disturbance,
separate SYNC-inputs are recommended (see below), supplied by +24 VDC.
SYNC (7-12)
D24 V input from sync switches, external axes. The input can be supplied with +24 V
I/O or an ex24 V voltage.
EXC, OVEXC
Common supply of all resolvers.
