Description
08
Apparent power
The actual apparent power of the motor as calculated by the device
09
Effective power
The actual effective power calculated by the device
10
Torque [%]
The actual torque calculated by the device
11
Field [%]
The actual field in the motor, as calculated by the device
12
Actual frequency ±
The analog voltage is proportional to the output frequency of the device, whereby the null point is
shifted to 5 V. For rotation to the right, values between 5 V and 10 V are output, and for rotation to
the left values between 5 V and 0 V.
13
Actual speed ±
This is the synchronous rotation speed calculated by the FI, based on the current setpoint, where
the null point has been shifted to 5 V. For rotation to the right, values from 5 V to 10 V are output
and for rotation to the left, values from 5 V to 0 V.
The measured speed is output via this function if servo mode is used.
14
Torque [%] ±
Is the actual torque calculated by the FI, whereby the null point is shifted to 5 V. For drive torques,
values between 5 V and 10 V are output, and for generator torque, values between 5 V and 0 V.
30
Setpoint freq. before ramp
displays the frequency produced by any upstream controllers (ISD, PID, etc.). This is then the
setpoint frequency for the power stage after it has been adjusted by the acceleration or braking
ramp (P102, P103).
31
Output via BUS PZD
the analog output is controlled via a bus system. The process data is directly transferred (P546,
P547, P548 = 20).

List of possible digital functions of the analog outputs
All relay functions described in parameter P434 can also be transferred via the analog output. If a
condition has been fulfilled, then there will be 10 V at the output terminals. Negation of the function
can be specified in parameter P419.
