SPEED LOOP
This function block contains parameters
for setting-up the speed loop. The block
is viewed in two menus on the MMI.
SETPOINTS
This MMI menu contains the setpoint
parameter reference inputs for the
function block.
Parameter Descriptions
PROP. GAIN
Speed loop PI proportional gain adjustment.
INT. TIME CONST.
Speed loop PI integral gain adjustment.
INT. DEFEAT
Inhibits the integral part of the speed loop PI control to give proportional only control.
ENCODER SIGN
Since the encoder feedback cannot be reversed electrically, the signal polarity can be reversed by
the control software.
SPEED FBK SELECT
Four options are available:
i) Armature voltage feedback
ii) Analog tachogenerator feedback
iii) Encoder feedback
iv) Analog / Encoder feedback
SETPOINT 1
Speed Setpoint 1 (Default Setpoint Sum 1 O/P).
SIGN 2 (A3)
Speed Setpoint 2 Sign.
