Analog inputs
For programmable analog inputs see chapter 6.12.2 for more details.
Self tuning of current regulator
See chapter 5.3.5.1.
R&L Search Command for current regulator self tuning execution
- Enable the drive (Enable Drive parameter= Enabled)
- Start the drive (Start/Stop parameter = Start).
Self tuning of speed regulator
(see chapter 5.3.5.2 for more details):
Fwd-Rev spd tune Direction of motor shaft rotation for the speed self tune test (Forward or Reverse; For-
ward is clock-wise as seen from shaft drive end).
Test T curr lim Torque current limit applied during Speed self tune test.
Start Speed regulator self tuning start command.
Inertia Total Inertia value at the motor shaft in Kg*m 2 (1 Kg*m 2 = 23.76 lb*ft 2 ).
Inertia Nw New total Inertia value at the motor shaft in Kg*m 2 identified during the speed self tune
procedure. (1 Kg*m 2 = 23.76 lb*ft 2 )
Friction Friction value (or Loss compensation) in N*m (1 N*m = 0.738 lb*ft).
Friction Nw New Friction value (or Loss compensation) in N*m identified during the speed self tune
procedure. (1 N*m = 0.738 lb*ft)
Speed P Proportional coefficient of the speed regulator in percentage
Speed P Nw New value of Proportional coefficient of the speed regulator in percentage computed
during the speed self tune procedure.
Speed I Integral coefficient of the speed regulator in percentage
Speed I Nw New value of Integral coefficient of the speed regulator in percentage computed during
the speed self tune procedure.
Take val Acquire the parameters after the self tune procedure (overwrite current values).
