Tab. 7-24: Parameter list of pump thermal protection
The pump may overheat at a low speed due to the oil volume required for the
pump cooling may not be adequate. The pump thermal protection function will
detect if pump speed is lower than the speed limitation [F4.36], and trigger
warning or error message according to [F4.37]. For details reference the follow-
ing table and figure.
This function can be activated by bit1 of F4.03 and is only active if drive is in op-
eration.
