Main power input Single-phase: L/N
Three-phase: L1/L2/L3
P1
BR
Braking resistor or connecting terminal: Used in cases where the
inverter frequently disconnects due to large load inertia or short
deceleration time (refer to specifications of braking resistor)
P1/ P

Descriptions of
CVP control circuit terminals
Symbol Description
R2A
R2B
Multifunctional terminal – Normal open
R1C
Common contact
R1B
Normal close contact
R1A
Normal open contact
Multifunctional output
terminals
Contact rated capacity:
(250VAC/1A or 30VDC/1A)
10V Frequency knob (VR) power source terminal (pin 3)
AIN
Analog frequency signal input terminal or multifunction input terminals S7 (H level:>8V, L
level:<2V, PNP only)
24V
Common contact for S1~S5 (S6, S7) in PNP (Source) input. Shift to PNP position (refer to
wiring diagram) of SW1 when used PNP input
COM
24G
AGND
1. Common contact and analog input /output signal for S1~S5 in NPN (Sink) input.
Shift to NPN position (refer to wiring diagram I) of SW1 when used NPN input.
2. AGND for AIN,
A
I2 and FM+ (analog input /output signal) & 24G for S1~S6 (digital input
/output signal in NPN (Sink) input). Shift to NPN position (refer to wiring diagram II) of SW1
when used NPN input.
FM+
The positive analog output for multifunction, the signal for output terminal is 0-10VDC (below
2mA).
S1
S2
S3
S4
S5
Multifunctional input terminals
S6
1. Multifunction input terminals (Digital terminal H level:>8V, L level:<2V, PNP only) or analog
input terminal AI2(0~10Vdc/4~20mA)
2. The V2.9 version (contains) above the edition, S6 only is the Multi-function input terminal
use, AI2 have replaced S6 to take analog input use. (Above wiring diagram refers for
2.2~30KW at 220V and 2.2~55KW at 440V only.)
