VLT 5000 Series protection:
• Electronic motor thermal protection against overload.
• Temperature monitoring of heat-sink ensures that the frequency converter cuts out if the temperature
reaches 90°C for IP 00, IP 20 and Nema 1. For IP 54, the cut-out temperature is 80°C. An
overtemperature can only be reset when the temperature of the heat-sink has fallen below 60°C.
For the units mentioned below, the limits are as follows:
- VLT 5122, 380-500 V, cuts out at 75°C and can be reset if the temperature has fallen below 60°C.
- VLT 5152, 380-500 V, cuts out at 80°C and can be reset if the temperature has fallen below 60°C.
- VLT 5202, 380-500 V, cuts out at 95°C and can be reset if the temperature has fallen below 65°C.
- VLT 5252, 380-500 V, cuts out at 95°C and can be reset if the temperature has fallen below 65°C.
- VLT 5302, 380-500 V, cuts out at 105°C and can be reset if the temperature has fallen below 75°C.
• The frequency converter is protected against short-circuiting on motor terminals U, V, W.
• The frequency converter is protected against earth fault on motor terminals U, V, W.
• Monitoring of the intermediate circuit voltage ensures that the frequency converter cuts out if the
intermediate circuit voltage becomes too high or too low.
• If a motor phase is missing, the frequency converter cuts out, see parameter 234 Motor phase mo nito r.
• If there is a mains fault, the frequency converter is able to carry out a controlled decelleration.
• If a mains phase is missing, the frequency converter will cut out when a load is placed on the motor.
