Logic Outputs
The HPV 600’s four programmable logic outputs
are opto-isolated. The outputs are normally
open and can withstand an applied maximum
voltage of 50VDC. When the outputs become
“true”, the output closes and are capable of
sinking up to 150mA between the logic output
terminal and the logic output common
HPV 600 Control Boards with the part number
(46S03708-xxxx) have four open collector or
open-emitter logic outputs. The figure below
shows the open-collector configuration. (TB1-
14).

HPV 600 Control Boards with the part number
(46S03740-xxxx) have four open collector logic
outputs.

Relay Outputs
The HPV 600’s two programmable relay logic
outputs are Form-C relays. They have both
normally open and normally closed contacts.
The specifications for each relays are as
follows:2A at 30VDC / 250VAC (inductive load)
Below shows the logic output terminals.

Encoder
The HPV 600 has an incremental encoder
option card that has connections for an
incremental two-channel quadrature encoder.
The drive’s encoder circuitry incorporates
resolution multiplication and complimentary
outputs.
Encoder Wiring
Use twisted pair cable with shield tied to chassis
ground at drive end, in order to minimize
magnetic and electrostatic pick-up current and to
minimize radiated and conducted noise.
Reasonable care must be taken when
connecting and routing power and signal wiring.
Radiated noise from nearby relays (relay coils
should have R/C suppressors), transformers,
other electronic drives, etc. may be induced into
the signal lines causing undesired signal pulses.
Power leads and signal lines must be routed
separately. Signal lines should be shielded,
twisted and routed in separate conduits or
harnesses spaced at least 12 inches apart from
power wiring. This protects the cable from
physical damage while providing a degree of
electrical isolation. Also, do not run cable in
