GV3000/SE drives set up for FVC regulation require an encoder for closed loop
operation. Encoder specifications are provided in table A.6. Drives set up for V/Hz
or SVC regulation do not require an encoder for feedback because they operate in
open loop mode.
Encoder connections are considered signal level wiring and, therefore, must be run
separate from control and power wiring. Reliance Electric recommends 18 AWG
unshielded twisted pair wires with 2-3 twists per inch for applications to a maximum
distance of 303 meters (1000 feet). The recommended Reliance Electric part
number is 417900-207CG, 18 AWG, 6 conductor (3 twisted pairs).
Motor Full Load Amps
Verify that the GV3000/SE output current rating is greater than the motor's full load
current (amps). Table 2.1 lists the output current values.
