Convo Inverter Cvfs1 Manual Repack [exclusive] Jun 2026

: Power down the drive completely, wait 10 minutes for the internal DC bus capacitors to discharge safely, and retorque all power and control screw terminals. Thermal cycling can loosen connections over time.

While there is no official "repack" document for the , you can effectively reset or reconfigure the unit using the standard operational procedures found in its technical documentation. Core Control & Commands

: Ensure the main input power supply is completely switched off before attempting any wiring work. convo inverter cvfs1 manual repack

Panel Potentiometer input 1: Digital Up/Down keys on keypad 2: Terminal Up/Down digital inputs 3: AVI Analog Input (0–10V) 5: ACI Analog Input (4–20mA) F0.04 Maximum Input Frequency 50.0Hz 50.0Hz to 999Hz (Establishes acceleration base) F0.05 Frequency Upper Limit 50.0Hz 50.0Hz to 999Hz (Hard limit for motor speed) Wiring and Terminal Control Setup

Verify AI1 (analog input 1) and GND are connected to potentiometer wiper and one end. Step 2 (parameter table): Check P1.01 (main frequency source). Must be = 1 (AI1). Step 3 (jumper section): Ensure jumper J1 is set to V (voltage) not I (current). Step 4 (repack tip): Measure voltage at AI1-GND while turning pot – should be 0–10V. Outcome: Jumper was incorrectly set to current. Fixed in 1 minute. : Power down the drive completely, wait 10
