Drive Operation on DeviceNet 7-6

Run/Stop Selection

The Drive can be configured to receive operation signals (Run, Stop, Forward, Reverse, and Multi-Function
Inputs) from the DeviceNet network, the external Drive terminals, or the Digital Operator.

There are two settings that determine the method of Run/Stop Control:

• Drive Parameter b1-02 setting
• Network Run/Stop Control setting
• Default Network Control

Drive Parameter b1-02 Setting

The Drive Parameter b1-02 setting can be accessed in various ways:

1. Parameter

b1-02

If this attribute equals ‘0’, run/stop control is from the Digital Operator
If this attribute equals ‘1’, run/stop control is from the external terminals
If this attribute equals ‘2’, run/stop control is from serial communications
If this attribute equals ‘3’, run/stop control is from an option PC board (DeviceNet)

2. Yaskawa Class 104, Instance 1, Attribute 2

Network Run/Stop Control Setting

The Network Control setting can be ‘Enabled’ or ‘Disabled’. The power-up setting is determined by the setting of
parameter b1-02. The setting can be changed any time after power-up via the DeviceNet network.

When Network Control is set to ‘1’, Drive parameter b1-02 is set to ‘3’ (option PC board) followed by an ACCEPT
command, and run/stop control is from the DeviceNet network. If Network Control is set to ‘0’, Drive parameter
b1-02 is set to the contents of the Default Control setting, EDS Parameter 13, followed by an ACCEPT command.

While the Drive is running, if an attempt is made to change from network control, DeviceNet will give a “Dnet
Error: Privilege Violation” error and will not allow write access to memory. The same happens if an attempt is
made to change from non-network control to network control. The Drive must be stopped before control may be
changed to or from network control.
