Write variables "TorqueScale" and "Drive_Mode"
The variables "TorqueScale" and "Drive_Mode" are AC drive prole objects
They are dened in the CIP library:
Variable Class Instance Aribute Data type Size
Drive_Mode 2a 1 6 SINT 1 byte
TorqueScale 2a 1 18 SINT 1 byte
•
Drive_Mode
The variable "Drive_Mode" has two valid sengs:
•
1: Velocity Mode
•
3: Torque Mode
•
TorqueScale
The variable "TorqueScale" refers to the real torque command by the following equaon:
Torque reference in TorqueScale = Nm * 2TorqueScale
Due to the seng of TorqueScale = 0, the torque reference (assembly output object 23,
bytes 4/5) is the real torque (= Nm * 20 = Nm * 1 = Nm).
Loading the value "2" as torque reference determines a torque limit of the drive of 2 Nm.
