XSMC: Mains contactor

MCCOM Fixed output for the mains contactor
250 V / 30 V
MCNO
AC
Maximum wire size 2.5 mm
Varistor protected
STOCOM Fixed output for safe torque off (STO) zero current monitor
250 V / 30 V
STONO
AC
Maximum wire size 2.5 mm
Varistor protected
Mains contactor ON command:
06.24.b07 Current controller status word 1

XSTO: Safe torque off

OUT1 For the drive to start, both connections (OUT1 to IN1 and IN2) must be closed. By default, the terminal block
has wires to close the circuit. Removing the wires will block the firing pulses.
IN1
Maximum wire size 2.5 mm
IN2
Current consumption per channel: 55 mA (continuous)

X205 Memory unit connection

The drive is equipped with a memory unit that is plugged into X205 on the SDCS-CON-H01. The
memory unit contains the firmware, the parameters and the application program (as option). It is
possible to handle the parameters by control panel, PC tool or overriding control. Changed parameters
are stored immediately in the memory unit.
In addition, the fault logger entries are stored in the memory unit during de-energizing the auxiliary
power.
When a drive is replaced, the parameter settings can be retained by transferring the memory unit from
the defective drive to the new drive.
WARNING
Do not remove or insert a memory unit when the thyristor power controller is powered.
After power-up, the drive will scan the memory unit. If different parameter settings are detected, they
are copied to the drive. This may take several minutes.
