Via the incremental encoder connection X8 a KTY resistor can be connected
to pin X8/5 and X8/8. The motor temperature is detected and integrated in
the drive monitoring.
The KTY resistor is monitored with regard to interruption and short circuit.
We recommend to always activate the KTY input when using motors which
are equipped with KTY resistors. This serves to prevent the motor from being
destroyed by overheating.
(
Stop!
The controller can only evaluate one KTY resistor! Do not
ƒ
connect several KTY resistors in series or parallel:
– The motor temperature would be measured incorrectly.
– The motors could be destroyed by overheating.
If several motors are operated on one controller, use thermal
ƒ
contacts (NC contacts) connected in series for motor
temperature monitoring.
To achieve full motor protection, an additional temperature
ƒ
monitoring with separate evaluation must be installed.
