SPAN
SPAN is the angle through which the dancer pot wiper must
rotate to cover the full speed range that the application requires.
The motor will not increase speed at any setting past this angle.
The minimum span of the wiper to obtain rated output from
these controls is 10°. To adjust SPAN:
1.
Set the dancer wiper to the desired maximum position.
2.
Adjust the SPAN trimpot until the desired maximum
motor speed has been reached.
MAXIMUM SPEED (MAX SPD)
The MAX SPD setting determines the motor speed when the
dancer potentiometer wiper is at the maximum cutoff point set
by the SPAN trimpot. It is factory set for maximum rated
speed.
To calibrate, set the MAX SPD trimpot to maximum (full CW).
Set the dancer potentiometer wiper to maximum. Adjust the
MAX SPD trimpot CCW until the desired maximum motor
speed is reached.
REGULATION (IR COMP)
The IR COMP trimpot setting determines the degree to which
motor speed is held constant as the motor load changes. It is
factory set for optimum motor regulation.
