MAXIMUM SPEED (MAX SPD)
The MAX SPD setting determines the maximum motor speed
when the speed adjust potentiometer, or voltage input signal is set
for maximum forward speed. It is factory set for maximum rated
motor speed.
To calibrate MAX SPD:
1. Set the MAX SPD trimpot full CCW.
2. Set the speed adjust potentiometer or voltage input signal for
maximum forward speed.
3. Adjust the MAX SPD trimpot until the desired maximum
forward speed is reached.
TACHOGENERATOR (for use with tachogenerator
feedback only)
Calibrate the TACH setting only when a tachogenerator is used.
The TACH setting determines the degree to which motor speed is
held constant as the motor load changes.
To calibrate the TACH trimpot:
1. Connect the tachogenerator to terminal SO502. The polarity is
“+” for T1 and “–” for T2 with the motor running in the
forward direction. The motor will run in the forward direction
when the voltage at terminal A1 is more positive than A2.
