3.15 Analogue and pulse outputs

Several monitors are available through the pulse output [EO] or the analogue output [AM].

C047
For the pulse train output there are two types of outputs, code "03", "08" and "15" outputs a pulse train with a 50% duty cycle
while the PWM has a fixed frequency of 156.25Hz were the duty cycle is changed depending on the output.

3.16 Torque limit

Torque limit function allows you to limit the motor output when sensorless vector control (SLV) is selected in A044. This func-
tion has limited accuracy and repeatability and is realiable only above 15 - 20Hz. You can choose between models using parame-
ter b040.
Quadrant specific setting mode (b040=00) in which individual torque limit value are applied on the four quadrants (forward
powering, reverse regeneration..) by torque limits 1 to 4 (b041 to b044)

(
Terminal-switching mode (b040=01) where the torque limit values set in torque limits 1 to 4 (b041 to b044) are switched
depending on the combination of the states of the torque limit switch terminals 1 and 2 (TRQ1 and TRQ2) assigned to digital
inputs.
Analog voltage input mode (b040=02) where the torque limit value is set by a voltage applied to the terminal O. Range 0 to
10V corresponds with torque limit range between 0 and 200% that is valid for all operating states.
If "TL" torque limit enable functions has been assigned to any of the multi-function inputs the setting of parameter b040 only is
valid when this input is ON. No torque limitation will be applied whe the input is OFF.
