Motor drive state, can be a combination of the
following:
0x0001 = RUN
0x0002 = STOP
0x0004 = ON
0x0008 = OFF
0x0010 = TOOL CHANGE START
0x0020 = TOOL CHANGE END
NOTE: When writing a new state value, the value can
only be a single state, not a combination of multiple
states, e.g. ON+RUN cannot be written simultaneously.

Profinet I/O gateway (Hilscher NT 50-RS-EN)
If the motor drive needs to be connected to a Profinet I/O device the Hilscher NT 50-RS-EN gateway can be used. The
gateway is connected to the motor drive via the DSUB-9 connector on the gateway and the J1 connector on the motor
drive. Below is the pinout for the DSUB-9 (X2 connector) found on the gateway:
A pull-up resistor of 10 kΩ is internally connected in the gateway to “RxD / TxD+”.
A pull-down resistor of 10 kΩ is internally connected in the gateway to “RxD / TxD–”.
Detailed documentation about the gateway and configuration tools can be downloaded from the Hilscher website:

50-rs-enmbrpns/
Configuration
The gateway comes pre-configured from Mirka as a Profinet I/O slave device. The “SYCON.net” software from Hilscher
can be used to re-configure the device. The “Ethernet Device Setup” software from Hilscher can be used to change
the network configuration, use the DCP protocol. The IP address usually needs to be re-assigned after a configuration
change.
The default configuration can be downloaded from the Mirka website www.mirka.com
