ABB MicroFlex e150 User Manual

60 Electrical installation: input / output
Analog I/O
The MicroFlex e150 provides:
• Two 12-bit resolution ±10 V analog inputs.
• One 12-bit resolution ±10 V analog output.
An analog input receives the torque / velocity reference signal when operating as an
analog drive (see CONTROLREFSOURCE in the Mint help file), or it can be used as a
general purpose ADC input.
 Analog inputs AIN0, AIN1
Location: X4, pins 3 & 7 (AIN0), 2 & 6 (AIN1), 5 (AGND).
The analog inputs pass through a differential buffer and second order low-pass filter
with a cut-off frequency of approximately 1.2 kHz.
In Mint, analog inputs can be read using the ADC keyword. See the Mint help file for
full details of ADC, ADCMODE and other related ADC... keywords.
Input circuit:
For differential inputs connect input lines to AIN+ and AIN-. Leave AGND
