P323/P333 Premagnetization time1/2
Setting range: 0–20s
The premagnetization value of the matching motor is set as the factory setting.
Premagnetization serves to establish a high motor torque and starts when the device
is enabled.
P324/P334 Slip compensation1/2
The parameter is only effective in "VFC," "VFC n-control" and "V/f" operating modes.
Setting range: 0–500min
-1
The value of the matching motor is set as the factory setting.
Increases the speed accuracy of the motor. If values are entered manually, the nom-
inal slip of the connected motor must be entered. A setting range of ± 20 % of the
nominal slip is permitted if a value other than the nominal slip is entered to com-
pensate for fluctuations between various motors.
P34. Motor protection
P340/P342 Motor protection1/2
Setting range: Off/One asynchronous motor/One servomotor
Depending on the motor connected (synchronous or asynchronous motor) this func-
tion can have the following effects.
Setting: Off
The function is not active.
Setting: ON asynchronous motor
The power section "PFA-..." takes over the thermal protection of the connected motor
electronically. In most cases, the motor protection function is comparable to standard
thermal protection (motor protection switch) but, in addition, it takes account of speed-
dependent cooling by the integrated fan. The motor utilization is calculated on the
basis of:
• Inverter output current
• Type of cooling
• Motor speed
• Time
The thermal motor model is based on the motor data entered in the
MOVITOOLS
®
MotionStudio engineering software and the operating conditions spe-
cified for the motor.
INFORMATION
If the motor also has to be protected against failure of the ventilation, blockage of air
ducts, etc., it is also necessary to employ protection in the form of a TF positive tem-
perature coefficient thermistor or TH bimetallic switch.
