Drive Operation on DeviceNet 7-12
The default torque_scale value is 0, which means the units are in N-m*(2 0 ) or N-m. If Torque Reference or
Actual Torque values are scaled too small to obtain an accurate reading, adjust the torque_scale to obtain a
readable value.
The torque_scale can be accessed in various ways:
1. EDS Parameter 25
The range is -9 to 0. The value is a unit less integer.
2. AC Drive Class 42, Instance 1, Attribute 24
The range is -9 to 0. The value is a unit less integer, but must be entered as a one byte hex number.
Example: -9 must be entered as F7h
If the Drive speed is being controlled with Polled I/O messages, then Assembly 22, 23, 121, 122, 124, or 126 are
the only methods available from the list above.
Methods 1, 2, and 6 conform to the DeviceNet AC Drive Device Profile. See Chapter 8 for more information.
