Function
POWER TERMINAL BOARD
Connection for commercial power (200-230 VAC or 380-460 VAC);
3-phase; 50⁄60 Hz.
Connection for 3-phase induction motor.
Connection for external braking resistor.
(Only on 10 Hp or less.)
Connection for external braking resistor via external braking unit.
(Only required on 15 Hp)
Connection for a dc link reactor on unit rated 100 Hp and greater.
These terminals are jumpered on units rated 75 Hp and less.
Connection for ground. Note: Be sure to ground the chassis to
prevent electrical shock & to reduce radio noise.
Connection point for single-phase, 460 ac power for backing up the
control circuit power when input starter is used (40 Hp and greater.)
Factory connection set at U1 for 400 - 460 VAC input.
Reconnect to U2 for 380 VAC input. (40 Hp and greater)
CONTROL TERMINAL BOARD
Common terminal for terminals 12, 13, C1 & V1, and FMA (Do not
connect to CM terminal or electrical noise immunity may be lost.)
When 0 to +10 VDC (0 to 5V) is input, the maximum frequency is
reached at +10 VDC (5V) and is proportional to output frequency
down to 0 VDC. Input impedance is 22K ohm. Must be isolated source.
Regulated +10 VDC power supply for frequency setting potentiometer,
10mA or less (13 to terminal 11.)
When the input signal is +4 to +20mA dc, the maximum frequency is
reached at 20mA and is proportional down to a minimum frequency
setting at 4mA. Input impedance is 250 ohm. Must be isolated source.
Reaches maximum output frequency at +/- 10 VDC (the output
freq. is proportional down to 0 VDC.) Input impedance is 22K ohms.
Must be isolated source.
Common terminal for control input commands, and FMP pulse
output signal. (Do not connect to terminal 11.)
Forward command via FWD-CM (closed). Reverse command via
REV-CM (closed). When FWD-CM is closed and REV-CM is closed
at the same time, the drive will decelerate to stop.
Motor will coast-to-stop with BX-CM (closed). (For use when
applying mechanical brake with drive in operation.) Note: If
BX-CM is opened with FWD or REV closed, the drive will start
operating.
