2.14 Frequecy input/output connection
The drive has the possibility to “read” two inputs in frequency.
The first input Encoder IN type. The input can receive signals in quadrature and frequency/sign,
(b42.5), from an incremental encoder to 5 Volt-DC as from standard LineDrive-RS422. Follow the
outline of connection for the reference of frequency, whether from an encoder or from an external
module:
The second input in frequency uses two digital inputs. The input can receive signals in quadrature
and frequency/sign, (b42.4), from IN2 and IN3 digital inputs to 24 Volt-DC. Follow the outline of
connection:
