Encoders for NORD AC Drives
NORD frequency inverters with encoder inputs are de-
signed to use TTL/RS422 encoders. There are also ad-
vantages in using an encoder with the 10-30VDC pow-
er supply system. The NORD inverters can use a wide
range of pulse counts, however the 1024PPR version
provides good performance with minimal interference
issues. A 4096 PPR encoder can also be used and will
provide increased precision in some applications, but
has some increased concerns with noise interference.
Recommended encoder: IG11P – 1024PPR/TTL/10-30VDC
Alternate encoder: IG41P – 4096PPR/TTL/10-30VDC
Absolute Encoder (AG)
Absolute encoders offer a unique value (voltage, bi-
nary count, etc.) for each mechanical position. When
an absolute encoder is powered up, the position of the
encoder is known. Absolute encoders are available in
single or multi-turn versions. The encoder is attached
under the fan cover with fi eld bus connection outside
the fan cover.
Absolute encoders can be provided to meet a variety
of specifi cations:
• Resolution: up to 17 bits of resolution per turn
(131,072 steps) with 4096 turns (12 bits of turns)
• Interfaces: Synchronous serial interface (SSI), SSI with
incremental track, Profi Bus, DeviceNet, CANopen,
CANlift, and other interfaces
