  • Page 40 7.5-7.9 General The motor thermal protection is to protect the motor from overheating. The SV9000 drive is capable of supplying higher than nominal current to the motor. If the load requires this high current there is a risk that motor will be thermally overloaded. This is true especially at low frequencies.

  • Page 44 SV9000 Motor Pump Enhanced Protection Application Page 39 (60) 7.12 Stall time The time can be set between 2.0—120 s. This is the maximum allowed time for a stall stage. There is an internal up/down counter to count the stall time. See figure 6.2-22. If the stall time counter value goes above this limit the protection will cause a trip (see parameter 7.10).
