7 PROFIBUS DP Communication
7.1 Introduction
As a PROFIBUS DP fieldbus adapter card that meets international PROFIBUS fieldbus
standards, the MD38DP2 expansion card can improve the communication efficiency
of the AC drive and implement the networking function, enabling the AC drive to be a
slave controlled by the fieldbus master. Besides PROFIBUS DP communication,
MD38DP2 also provides the CANlink communication interface.
This user guide is applicable to the MD38DP2 expansion card with software of version
1.09 or later (you can query the version by viewing the parameter U0‑67 of the AC
drive after the card is installed and powered on).
7.2 Installation
The MD38DP2 card is embedded in the MD520 series AC drive. Before installation, cut
off the power supply of the AC drive and wait for about 10 minutes until the charging
indicator of the AC drive becomes off. Then, insert the MD38DP2 card into the AC drive
and fasten the screws to prevent the signal socket between boards from being
damaged by the pulling force of the external signal cable. "
