PT100 evaluation unit
The PT100 evaluation unit can monitor up to 6 sensors. The sen-
sors can be connected in a two-wire or three-wire system. The
limit values can be programmed by the user for each channel.
In the factory setting, the measurement channels are divided
into two groups of three channels. With motors, for example,
three PT100 units can, therefore, be monitored in the stator wind-
ings and two PT100 units in the motor bearings. Channels that
are not used can be suppressed using appropriate parameter
settings.
The output relays are integrated into the internal fault and shut-
down sequence of the converter. The customer can also tap the
event logs via two free fault signal relays. Two user-programma-
ble analog outputs (0/4 mA to 20 mA or 0/2 V to 10 V) are also
available for integration in a higher-level controller.
L87
Insulation monitoring
An insulation monitor must be used if the converter is operated
on an isolated network. This device monitors the complete elec-
trically connected circuit for insulation faults.
An alarm is output in the event of a fault.
Attention
: Only one insulation monitor can be used in an electri-
cally connected network.
Since the response philosophy when a ground fault occurs in the
insulated network can be different, the output relays are avail-
able for integration into a control system on the plant side. It is
also possible to integrate the outputs into the converter monitor-
ing on the plant side.
Insulation monitoring can be supplied on request for drive con-
verter cabinet units with power units connected in parallel.
M06
Base 100 mm high, RAL 7022
The additional cabinet base allows larger bending radii for ca-
bles (inlet from below) and the routing of them within the cabinet
base.
The cabinet base is always colored RAL 7022. A special color is
not possible. It is delivered completely fitted with the cabinet.
The height of the operator panel changes accordingly.
M07
Cable plinth 200 mm high, RAL 7035
The cable wiring compartment is made of stable sheet steel and
increases the flexibility for the cable connection (inlet from be-
low) and allows routing of cables within the wiring compartment.
It is delivered completely fitted with the cabinet. The height of the
operator panel changes accordingly.
Attention
: The cable wiring compartment is colored RAL 7035 as
standard. If a special color is requested for the cabinet (order
code Y 09), the cable wiring compartment is also painted in this
color.
