All the output pins can be converted to input pins if necessary. Please contact
Zapi for further information
4.4 Incremental encoder
The VCM is fit for two incremental encoder interfaces (PREMIUM version).
These interfaces have the following characteristics
1. It can read signal from encoders with push-pull output or with open-
collector output.
2. Input voltage range [0; 12]V
3. Input impedance >3 k
The encoder power supply can be +5V or +12 V

VERY IMPORTANT
It is necessary to specify in the order the type of encoder used, in terms of
power supply, electronic output and n° of pulses for revolution, because
the logic unit must be set in the correct way by Zapi.
