7.4 Example: PLC Programming

In this example, PPO type 6 is placed in the following input/output address:
Input

address
Set-up Status word MAV
Illustration 7.2 PPO Type 6 Placed in the Input/Output Address
This network sends a start command (047C hex) and a
reference (2000 hex) of 50% to the frequency converter.
Illustration 7.3 Network Sends Start Command and Reference
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.

torque input
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
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
This network activates relay 02.
