NOTICE: Do not tighten screws beyond the specified tightening torque. Failure to comply may damage the terminal block.
NOTICE: Use shielded twisted-pair cables as indicated to prevent operating faults. Improper wiring practices could result in drive or
equipment malfunction due to electrical interference.
Connect control wires as shown in the following figure:
A – Control terminal block
B – Avoid fraying wire strands when
stripping insulation from wire. Strip
length 5.5 mm.
C – Single wire or stranded wire
A – Drive side
B – Connect shield to ground terminal
of drive.
C – Insulation
When setting the frequency by analog reference from an external potentiometer, use shielded twisted-pair wires and ground
the shield of twisted-pair wires to the ground terminal of the drive.
NOTICE: The analog signal lines between the drive and the operator station or peripheral equipment should not exceed 50 meters when
using an analog signal from a remote source to supply the frequency reference. Failure to comply could result in poor system performance.
A – Drive
B – Ground terminal (shield
connection)
C – (RP) Pulse train (maximum 32 kHz)
D – (+V) Frequency setting power
source +10.5 Vdc maximum 20 mA
