This network sends a start command (047C hex) and a
reference (2000 hex) of 50% to the frequency converter.
Illustration 7.3 Network Sends a Start Command and a
Reference of 50% to the Frequency Converter.
This network reads the motor torque from the frequency
converter. A new reference is sent to the frequency
converter because the motor torque (86.0%) is higher than
the compared value.
Illustration 7.4 Network Reads the Motor Torque from the
Frequency Converter
This network reads the status on the digital inputs from
the frequency converter. If digital input 18 is On, it stops
the frequency converter.
Illustration 7.5 Network Reads the Status on the Digital Inputs
from the Frequency Converter
This network reverses the motor when digital input 19 is
ON, because parameter 8-54 Reversing Select is
programmed to Logic AND.
Illustration 7.6 Network Reverses the Motor When Digital
Input 19 is ON
This network activates relay 02.
Illustration 7.7 Network Activates Relay 02
