Table 5: Terminal Identification/Function
Terminal Terminal
Label Name Function
POWER TERMINAL BOARD
L1, L2, ac Supply Line Connection for commercial power (200-230 VAC or 380-460 VAC);
L3 Input Terminals 3-phase; 50⁄60 Hz.
U, V, W Drive Output Connection for 3-phase induction motor.
Terminals
P+, DB External Braking Connection for external braking resistor.
Resistor Terminals (Only on 10 Hp or less.)
N-, P+ External Braking Connection for external braking resistor via external braking unit.
Unit Terminals (Only required on 15 Hp)
P+, P1 DC Reactor Connection for a dc link reactor on unit rated 100 Hp and greater.
These terminals are jumpered on units rated 75 Hp and less.
E (G) Ground Terminal Connection for ground. Note: Be sure to ground the chassis to
prevent electrical shock & to reduce radio noise.
RO, TO Control Power Connection point for single-phase, 460 ac power for backing up the
Auxiliary Input control circuit power when input starter is used (40 Hp and greater.)
U1, U2 Auxiliary Transformer Factory connection set at U1 for 400 - 460 VAC input.
Taps Reconnect to U2 for 380 VAC input. (40 Hp and greater)
CONTROL TERMINAL BOARD
Frequency Setting Common terminal for terminals 12, 13, C1 & V1, and FMA (Do not
11 Common Terminal connect to CM terminal or electrical noise immunity may be lost.)
12 Frequency Setting When 0 to +10 VDC (0 to 5V) is input, the maximum frequency is
Voltage Input reached at +10 VDC (5V) and is proportional to output frequency
down to 0 VDC. Input impedance is 22K ohm. Must be isolated source.
13 Frequency Setting Regulated +10 VDC power supply for frequency setting potentiometer,
Voltage Output Term. 10mA or less (13 to terminal 11.)
C1 Frequency Setting When the input signal is +4 to +20mA dc, the maximum frequency is
Current Input reached at 20mA and is proportional down to a minimum frequency
setting at 4mA. Input impedance is 250 ohm. Must be isolated source.
V1 Voltage Input Reaches maximum output frequency at +/- 10 VDC (the output
Auxiliary Terminal freq. is proportional down to 0 VDC.) Input impedance is 22K ohms.
Must be isolated source.
CM Control Circuit Common terminal for control input commands, and FMP pulse
Common Terminal output signal. (Do not connect to terminal 11.)
FWD Forward Command
Input Terminal
Forward command via FWD-CM (closed). Reverse command via
REV-CM (closed). When FWD-CM is closed and REV-CM is closed
Reverse Command at the same time, the drive will decelerate to stop.
REV Input Terminal
BX Motor Coast-To-Stop Motor will coast-to-stop with BX-CM (closed). (For use when
Input Terminal applying mechanical brake with drive in operation.) Note: If
BX-CM is opened with FWD or REV closed, the drive will start
operating.
