Operation
Frequency Reference Signal – Speed potentiometer/0 to +10 VDC
– 4 to 20 mA
– 0 to
±
10 VDC (Standard on 40 Hp and greater) (Option on 1/2 to 30 Hp)
Input Signal (contact type) Forward, reverse, self-holding selection (when operation is 3-wire), multi-step
speed setting (7-step), multiple accel/decel time settings (4 settings),
coast-to-stop, external alarm, and reset.
External Output Signals One Dry Form "C" alarm output contact rated 250 VAC, 0.3 amp.one auxiliary run
contact rated 250 VAC, 0.3 amp (available only on 40 Hp and above ratings.)
5 – Open collector outputs each rated 24 VDC, 50mA from external power.
– Drive Run
– Time-up signal during pattern mode
– Frequency equivalence signal – Undervoltage detection
– Overload early warning – Keypad operation
– Auto restart mode – Torque limiting mode
– Cycle completion pattern mode – Auto reset mode
Protective Functions: – Stall prevention – Undervoltage
– Momentary power failure – Overcurrent
– Drive overheating – Overvoltage
– External faults – Link error
– CPU malfunction – Communication error
– Motor overload – Ground fault
(electronic thermal)
Frequency Meter Output Signal Pulse frequency (6 to 100) times output frequency.
Analog - 0 to +10 VDC (adjustment range of 6.5 to 10.3 VDC)
Keypad Digital Display - 4 digit LED
Graphic Display - LCD, with brightness control
Drive Operation Output frequency, output current, output voltage, motor speed, line speed (m/min),
machine speed (r/min), torque limit (driving), torque limit (braking), and motor torque.
Set frequency is displayed when not in Run or Program Mode.
