Chapter 2 Installation and Wiring | NOTE: Control signal wiring size: 18 AWG (0.75 mm 2 ) with shielded wire. Analog inputs (AVI, ACM) wind each wires 3 times or more around the core Digital inputs (MI1~MI6, DCM) General NOTE If a filter is required for reducing EMI (Electro Magnetic Interference), install it as close as possible to AC drive. EMI can also be reduced by lowering the Carrier Frequency. DANGER! Damaged insulation of wiring may cause personal injury or damage to circuits/equipment if it comes in contact with high voltage. 2-10 Revision 2016/03, 6ELE, V1.14 Terminal Symbol Terminal Function Factory Settings (NPN mode) ON:

Output Frequency (Pr.01.00) Selection: Pr.02.00, Pr.02.09, Pr.10.00 Set-up: Pr.04.14 ~ Pr.04.17 ACM Analog control signal (common) Common for AVI= and AFM AFM Analog output meter ACM circuit AFM 0~10V potentiometer Max. 2mA internal circuit ACM 0 to 10V, 2mA Impedance: 47Ω Output current 2mA max Resolution: 8 bits Range: 0 ~ 10VDC Function: Pr.03.03 to Pr.03.04 NOTE The voltage output type for this analog signal is PWM. It needs to read value by the movable coil meter and is not suitable for A/D signal conversion.
Analog input signals are easily affected by external noise. Use shielded wiring and keep it as short as possible ( bring improvement. If the analog input signals are affected by noise from the AC motor drive, please connect a capacitor (0.1 µ F and above) and ferrite core as indicated in the following diagrams: C ferrite core AVI ACM When using contacts or switches to control the digital inputs, please use high quality components to avoid contact bounce. Keep control wiring as far away as possible from the power wiring and in separate conduits to avoid interference. If necessary let them cross only at 90º angle.
The AC motor drive control wiring should be properly installed and not touch any live power wiring or terminals.
