Actual Torque Display
Displays the actual torque in newtonmeter. During open-loop operation (CP.32 = 0)
value 0 is always shown.
Resolution: 0,1 Nm
max. tolerance: approx. ±30 % in base speed range (see page 4.3.4)
(In the field weakening range larger tolerances are possible)
Speed Reference Display
Displays the speed reference at the output of the ramp generator in rpm.
When the modulation is switched off the setpoint 0 rpm is displayed.
Resolution: 0,5 rpm
positive speed:
direction of rotation "forward"
negative speed:
direction of rotation "reverse"
acceleration time

[rpm]
Defines the time needed to accelerate from 0 to 1000 rpm. The actual acceleration
time is proportional to the speed change (D n).
