Reference

Handling

■ Handling of single references

Using a single reference, only one active reference

signal is connected, either in the form of an external

or in the form of a preset (internal) reference.

The external reference can be voltage, current,

frequency (pulse) or binary via the serial port. Two

examples are given below of the way the single

references are handled by the frequency converter.

Exter-

nal

Speed or torque reference

term 53 (±10 V)

term 54 (±10 V)

term 60 (0/4 - 20 mA)

term 17 or 29 (frequency)

RS 485

Single ref

Preset references (parameter 215 -

218)

Example 1:

External reference signal = 1 V (min) - 5 V (max)

Reference = 20 - 1500 rpm

Configuration (parameter 100) - Speed control,

closed loop.

Example 2:

External reference signal = 0 V (min) - 10 V (max)

Reference = 1500 rpm ccw - 1500 rpm cw

Configuration (parameter 100) - Speed control,

closed loop.
