9 Application Examples
9.1 E.g.: Process Data with PPO Type 6
This example shows how to work with PPO type 6, which consists of Control Word/Status Word and Reference/Main Actual
Value. The PPO also has two additional words, which can be programmed to monitor process signals:
PCD
0 1 2 3
CTW MRV PCD[2] PCD
From Controller 04 7C 20 00 00 00 00 00
STW MAV PCD[2] PCD[3]
From Drive 0F 07 20 00 3F A6 00 08
Byte # 1 2 3 4 5 6 7 8
Table 9.1
The application requires monitoring of the motor torque and digital input, so PCD 2 is set up to read the current motor
torque. PCD 3 is set up to monitor the state of an external sensor via the process signal digital input. The sensor is
connected to digital input 18.
An external device is also controlled via control word bit 11 and the built-in relay of the frequency converter. Reversing is
permitted only when the reversing bit 15 in the control word and the digital input 19 are set to high.
For safety reasons the frequency converter will stop the motor if the PROFINET cable is broken, the master has a system
failure, or the PLC is in stop mode.
