MD‑SI‑DP1 Communication
‑192‑
Parameter Group
Address
F0 to FF 0x00 to 0x0F
A0 to AF 0x40 to 0x4F
For example, the RAM address of F0‑10 is 0x000A.
PZD Data
The PZD data enables the master to modify and read AC drive data in real time and
perform periodic data exchange. The data communication addresses are directly
configured by the AC drive. The functions of PZD data are as follows:
● Setting the AC drive control command and target frequency in real time
● Reading the current state and running frequency of the AC drive in real time
● Exchanging function parameter and monitoring parameter data between the AC
drive and PROFIBUS master in real time The PZD is used for periodic data
exchange between the master and the AC drive, as described in the following
table.

PZD1
AC drive command word (command source set to
communication)
0: No command
01: Run in forward direction
02: Run in reverse direction
03: Jog in forward direction
04: Jog in reverse direction
05: Coast to stop
06: Decelerate to stop
07: Reset upon fault
PZD2
AC drive target frequency (frequency reference source set to
communication; value unit determined by the AC drive while
Hz is used as an example here)
The frequency reference ranges from 0 to F0‑10.
When F0‑22 is set to 1, the frequency range is 0.0 Hz to 3200.0
Hz.
When F0‑22 is set to 2, the frequency range is 0.00 Hz to
320.00 Hz.
When the reference target frequency exceeds F0‑10, the AC
drive does not respond to the frequency reference.
