Express OTR parameter (motor torque) as a value via serial communication on the ATV32 drive.
ATV32 series drives.
All models, All serial numbers.
OTR in the drive is displayed as 0 to 300% but 0-300 is not read from the communication registers, the number is different. How do these correlate?
Motor torque, OTR, is displayed by the drive as percentage of nominal motor torque as a value between 0% and 300%.
When reading motor torque over the network from register 3205, it will be displayed as a value between 0 and 8192. 0 = 0% torque, 8192 = 300% torque. When the motor is running at nominal torque, reading parameter 3205 will return the number 2731.
