Motor temperature monitoring with PTC or thermal contact
PTC resistors according to DIN 44081 and DIN 44082 can be connected via
the terminal inputs T1 and T2. The motor temperature is measured and
integrated into the drive monitoring.
A thermal contact (NC contact) can also be connected to T1 and T2. Lenze
three−phase AC motors provide thermal contacts as default.
When using motors equipped with PTC resistors or thermostats, we
recommend to always activate the PTC input. This prevents the motor from
being destroyed by overheating.
(
Stop!
ƒ
The motor temperature monitoring may only be connected to
T1, T2 if the cable is terminated with a PTC or thermal contact
(NC contact) on the motor side.
– An "open" cable acts like an antenna and can cause faults on
the drive controller.
– Input signals at T1, T2 are processed with a delay of 2 s.
ƒ
The drive controller can only evaluate one PTC resistor! Do not
connect several PTC resistors in series or in parallel:
– The motor temperature would be measured incorrectly.
– The motors could be destroyed by overheating.
ƒ
If you operate several motors on a drive controller, use
thermal contacts (NC contacts) for motor temperature
monitoring and connect these in series.
ƒ
To achieve full motor protection, an additional temperature
monitoring with separate evaluation must be installed.
