A
Analog reference
A signal transmitted to the analog inputs 53 or 54 (voltage or current).
Current input: 0–20 mA and 4–20 mA
Voltage input: 0–10 V DC
Analog inputs
The analog inputs are used for controlling various functions of the drive.
There are 2 types of analog inputs:
Current input, 0–20 mA, and 4–20 mA
Voltage input, 0 V DC to +10 V DC
Analog outputs
The analog outputs can supply a signal of 0–20 mA, 4–20 mA.
B
Break-away torque

(3)
Bus reference
A signal transmitted to the serial communication port (FC port).
C
Control command
Functions are divided into 2 groups.
Functions in group 1 have higher priority than functions in group 2.
Group 1
Reset, coast stop, reset and coast stop, quick stop, DC brake,
stop, the [OFF] key.
Group 2
Start, pulse start, reversing, start reversing, jog, freeze output.
D
Digital inputs
The digital inputs can be used for controlling various functions of the drive.
Digital outputs
The drive features 2 solid-state outputs that can supply a 24 V DC (maxi-
mum 40 mA) signal.
F
f
M
Motor frequency.
f
M,N
Rated motor frequency (nameplate data).
f
MAX
Maximum compressor frequency.
