📋 Understanding the VSX Model Number

Every VSX drive’s nameplate encodes its specification in the model number. Here’s how VSX48-003-20CEB breaks down:

Code Position	Meaning
VSX	Product series — VSX = General purpose drive
48	Input AC voltage level — 380–480V AC / 540V DC
003 … 112	Rated current code (A) — from 003 (2.5A) up to 112 (112A)
20	Protection class — IP20
C	Control panel — C = Standard panel
N / E	EMC filter — N = No filter, E = EMC filter fitted
B / –	Brake chopper — B = Brake chopper fitted, – = without

💡 A ‘-XS’ suffix on the model number denotes a drive with a 7-segment LCD display.

🔌 Wiring the VSX Drive

The VSX comes in two wiring layouts depending on power range: 0.75–2.2kW models have a simpler I/O set, while 4–55kW models add extra digital inputs, a second open-collector output, and a third analog input.

Main power & motor circuit (both ranges)

✅ L1, L2, L3 — 3-phase 415V, 50/60Hz supply, through an MCCB
✅ U, V, W — output to the motor
✅ Earth (⎓) — motor and drive frame earthing
✅ (−), (+), PB — external braking resistor connection

Control terminals

Terminal	0.75–2.2kW	4–55kW	Function
Digital inputs	5 (DI1–DI4, DI7)	7 (DI1–DI7)	Max input frequency 200Hz (100kHz for DI7). Impedance 2.4kΩ, voltage 9–30V
Digital outputs	1 (Y2/HO)	2 (Y1, Y2/HO)	0–24V / 0–50mA. Y2/HO doubles as a high-speed pulse output, up to 100kHz
Analog inputs	2 (AI1, AI2)	3 (AI1, AI2, AI3)	DC 0–10V / 0–20mA (AI3 is bipolar, −10V ~ +10V). Impedance 250kΩ (voltage) / 250Ω (current)
Analog outputs	2 (AO1, AO2)	2 (AO1, AO2)	DC 0–10V / 0–20mA, impedance ≥ 10kΩ
Relay outputs	2 (R1, R2)	2 (R1, R2)	250V AC/3A (cosΦ=0.4) or 30V DC/1A
RS485	1 (485+, 485−)	1 (485+, 485−)	Modbus communication, 4800–115200 bps

⚠️ Always wire and check connections with the drive fully powered down and the DC bus capacitors discharged. Route control wiring separately from the motor power cable to avoid electrical noise affecting the analog signals.

💻 Programming & Commissioning the VSX Drive

There are three ways to configure a VSX drive: the built-in keypad, the optional graphical LCD keypad, or CG’s free EmoWizard PC software.

Using the keypad

💡 Typical first-run sequence: power up the drive → confirm the display shows a frequency (e.g. 50.00Hz) → navigate into the parameter menu and set the motor nameplate data (rated voltage, current, frequency, poles) — the VSX can store two separate groups of motor parameters if you need to switch between two motors → set the command source (keypad, terminal, or RS485) and the frequency reference source to match your wiring → press RUN to test rotation direction at a low frequency, then bring it up to speed.

Optional graphical LCD keypad

✅ Quick, easy parameter setting with a clear graphical display
✅ Multi-row display of drive status
✅ Real-time display of motor speed, current, voltage and frequency
✅ Graphical trends, system performance and waveform display
✅ Parameter backup and download between drives
✅ Detailed fault descriptions and alarm indicators for troubleshooting
✅ Customizable screen for your preferred parameters
✅ Forward/reverse buttons to directly control motor rotation direction

Using EmoWizard software

For faster commissioning and troubleshooting, CG’s EmoWizard software connects to the drive over USB/RS485 and gives you:

✅ A graphical control panel to start/stop and adjust speed from a PC
✅ A built-in oscilloscope to plot live drive statistics while tuning
✅ Full parameter read/write and comparison, so a working configuration can be saved and copied to other drives
✅ Real-time fault diagnostics

❓ Frequently Asked Questions

What’s the difference between Heavy Duty and Normal Duty ratings?

✅ Heavy Duty gives a higher overload margin (200% for 1s) for constant-torque loads like extruders, cranes and hoists. Normal Duty gives a higher continuous output current for variable-torque loads like fans, blowers and pumps, with a lower overload margin (160% for 1s).

Can the VSX drive run with an encoder for closed-loop feedback?

✅ Yes — on drives rated 4.0kW and above, a range of PG (pulse generator) cards is available for differential, open-collector, UVW, Sin-Cos and resolver-type encoders, enabling closed-loop vector control.
