Adjustment of converter rated currents
Base Drive Panels are designed to continuously operate at the converter US rated current and then provide
150% overload current for 60 seconds. In order to meet this requirement it is mandatory that P067 be set to a
value of 5. The IEC Class 1 rating provides a higher continuous current but has no overload capability. The
fuses, contactor, power terminals, and power wiring used on base drives have been selected based on the US
rating. Failure to set P067 on Base Drive Panels to the US rating may cause damage to Base Drive Panel
components and void warranty.
Set parameter P067 = 5 “U.S. Rating“.
Set parameter P075 = 1 to allow dynamic overload capability.
3 Adjustment to actual converter supply voltage
P078.001 . . . Supply voltage for armature circuit (in volts)
P078.002 . . . Supply voltage for field circuit (in volts)
4 Input of motor data
The motor data as given on the motor rating plate must be entered in parameters P100, P101, P102 and P114.
P100 . . . Rated armature current (in amps)
P101 . . . Rated armature voltage (in volts)
P102 . . . Rated field current (in amps)
P114 . . . Thermal time constant of motor (in minutes). If not known use the default 10-minute value.
5 Actual speed sensing data
5.1 Operation with analog tachometer
P083 = 1: The actual speed is supplied from the “Main actual value” channel (K0013)
(terminals XT.103, XT.104)
P741 Tachometer voltage at maximum speed (– 270,00V to +270,00V)
