Functional Description
ru. 1 Actual speed display
Adr.
2001h
The displayed value depends on cn.3.
cn.3 = 0 (default) The actual speed is calculated from the actual frequency and the adjusted dr-parameters. This
calculated value corresponds to the synchronous speed, i.e. the slip occurring at the motor is not
taken into account. For a correct speed indication it is necessary to enter the motor data in the dr-
parameters.
cn.3 = 1 or 2 The current actual speed of the encoder interface (option) is displayed. The measured value
corresponds to the real slip-afflicted actual speed.
A counter-clockwise rotating field (reverse) is represented by a negative sign. Precondition is the correct phase connection
of the motor.
For a closed-loop-controlled system it is imperative to ensure the correct phase connection, otherwise the
controllers would run into their limit.
ru. 3 Actual frequency display
Adr.
2003h
The displayed actual frequency corresponds to the rotary field frequency at inverter output. A counter-clockwise rotating
field (reverse) is represented by a negative sign. Precondition is the correct phase connection of the motor. With ud.10
the display can be standardized to a resolution of 0,1 Hz.
ru. 4 Setpoint speed display
Adr.
2004h
The setpoint speed is derived from the set frequency (ru.6) and the adjusted motor data (dr-parameters). For a correct
speed indication it is therefore necessary to enter the motor data in the dr-parameters. A counter-clockwise rotating
field (reverse) is represented by a negative sign (see ru.1). Precondition is the correct phase connection of the motor.
