Introduction
This manual contains the very basic information about installing the
FEN-21 Resolver Interface. For complete documentation see
Resolver Interface User's Manual (3AFE68784859 [English])

Safety instructions

WARNING! All electrical installation and maintenance work on the drive
must be carried out by qualified electricians.
The drive and adjoining equipment must be properly earthed.
Do not attempt any work on a powered drive. After switching off the
mains, always allow the intermediate circuit capacitors 5 minutes to
discharge before working on the frequency converter, the motor or the
motor cable. Lock out and tag out. Check (with a voltage tester) that the
drive is in fact discharged before beginning work.
These warnings are intended for all who work on the drive. Ignoring the
instructions can cause physical injury or death, or damage the equipment.
For complete safety instructions see the drive manuals.
Compatibility
Resolvers
The FEN-21 is compatible with resolvers, which are excited by sinusoidal
voltage (to the rotor winding), and which generate sine and cosine
signals proportional to the rotor angle (to stator windings). Amplitude
and frequency of the excitation signal can be adjusted in range 4...12
V
rms
sine and cosine signals remains in range 2...7 V
TTL Encoders
The FEN-21 is compatible with TTL incremental encoders with
1...65535 pulses / rev and supports reference mark.
