Input of motor data

In the parameters below, the motor data must be entered as specified on the motor rating plate.

P100 . . . Rated armature current (in amps)

P101 . . . Rated armature voltage (in volts)

P102 . . . Rated field current (in amps)

P104 . . . Speed n

P105 . . . Armature current I

P106 . . . Speed n

P107 . . . Armature current I

P108 . . . Maximum operating speed n

P109 . . . 1 = speed-dependent current limitation active

P114 . . . Thermal time constant of motor (in minutes)

(if necessary: activate fault signal F037 with P820!)

Actual speed sensing data

Operation with analog tacho

Operation with pulse encoder

Selecting a pulse encoder type (pulse encoder types see below)

0 No encoder/"Speed sensing with pulse encoder" function not selected

1 Pulse encoder type 1

2 Pulse encoder type 1a

3 Pulse encoder type 2

4 Pulse encoder type 3

1. Pulse encoder type 1

(in amperes)

(in amperes)

The actual speed is supplied from the "Main actual value" channel (K0013)

(terminals XT.103, XT.104)

Tacho voltage at maximum speed (– 270,00V to +270,00V)

The actual speed is supplied by the pulse encoder (K0040)

Encoder with two pulse tracks mutually displaced by 90° (with/without zero marker)
