Basic Wiring Diagram - Savch S3100E Series User Manual

2.4 Basic Wiring Diagram

Wiring of AC motor drive can be divided into two parts, the main circuit and control circuit. After removing the
cover, terminals of main circuit and control circuit shall be found. Users must connect terminals as diagram
shows.
The following diagram is the standard wiring diagram of S3100E series AC motor driver. If only digital control
panel was used, only main circuit terminal wiring applicable.

Remarks:
1. The external terminal has two AVI inputs (AVI1, AVI2), one of which is shared with ACI and can be switched to
each other.
2. Analog current frequency command ACI:It can switch 4~20mA or 0~+10V as input signal according to J3.
3. There are 5 multi-function input terminals (MI1~MI5) in the external terminal, and the configuration input can be
selected.
4. The external terminals have 2 open collector outputs (MO1, DFM).
5. The external terminal has one relay output (RA-RB-RC).
6. The power of 22kW and above can be equipped with I/O expansion card: HCA-EIO-AO/MC1, the whole
machine realizes 2 analog (voltage/current optional) signals + 2 relay outputs.
7. The DC reactor, braking unit and braking resistor are selected according to the requirements. When using the
DC reactor, please remove the short-circuit copper sheet between P1 / P (+) before connecting.
