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
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
The analog outputs can supply a signal of 0–20 mA, 4–20 mA.
(1)
A signal transmitted to the serial communication port (FC port).
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.
The digital inputs can be used for controlling various functions of the drive.
The drive features 2 solid-state outputs that can supply a 24 V DC (maxi-
mum 40 mA) signal.
Motor frequency.
Rated motor frequency (nameplate data).
Maximum compressor frequency.
