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 Range: ENABLED/DISABLED
Speed loop PI proportional gain adjustment.
INT. TIME CONST. Range: 0.001 to 30.000 SECS
Speed loop PI integral gain adjustment.
INT. DEFEAT Range: ON/OFF
Inhibits the integral part of the speed loop PI control to give proportional only control.
ENCODER SIGN Range: POSITIVE/NEGATIVE
Since the encoder feedback cannot be reversed electrically, the signal polarity can be reversed by
the control software.
SPEED FBK SELECT Range: See below
Four options are available:
i)
Armature voltage feedback
ARM VOLTS
ii) Analog tachogenerator feedback
ANALOG TACH
iii) Encoder feedback
ENCODER
iv) Analog / Encoder feedback
ENCODER / ANALOG
SETPOINT 1 Range: -100.00 to 100.00 %
Speed Setpoint 1 (Default Setpoint Sum 1 O/P).
SIGN 2 (A3) Range: POSITIVE/NEGATIVE
Speed Setpoint 2 Sign.
