Benshaw PowerPro
™
High Performance
Single AC Drive
Nonparameter Data
Status data (read-only)
Group U (monitoring parameters), AC drive fault information
and AC drive running status
Control parameters (write-only)
Control commands, communication setting values, DO
control, AO1 control, AO2 control, high-speed pulse (FMP)
output control and parameter initialization
1. Status Data
Status data includes group U (monitoring parameters), AC drive fault description and AC
drive running status.
Group U (monitoring parameters):
For details about Group U, refer to 6.2.3 Monitoring Parameters. The communication
address is as follows:
The high 16 bits in communication address of U0 to UF is 70 to 7F and the low 16 bits
indicate the function code number in the group. For example, the communication address
of U0-11 is 700BH.
AC drive fault description:
Communication address of the drive fault information is 8000H. You can obtain current fault
codes by using host computer to read the address. For fault codes, refer to definition of
F9-14 in Appendix C of this manual
AC drive running status:
When the drive running status is read via communication, the communication address
is 3000H. You can obtain current running status information of the AC drive by reading
the address. The running status is defined in the following table.
Communication Address of
AC Drive’s Running Status
Status Definition
3000H
1: Forward run
2: Reverse run
3: Stop
2. Control Parameters
The control parameters include control command, communication setting values,
DO control, AO1 control, AO2 control, high-speed pulse (FMP) output control and
parameter initialization.
Control commands
When F0-02 (Running command selection) is set to 2 (communication control), you can
implement control such as start/stop of the AC drive by using communication address.
The control commands are defined in the following table.

2: Reverse run
3: Forward jog
4: Reverse jog
5: Coast to stop
6: Decelerate to stop
7: Fault reset
