* These settings apply when using a 5000W Master Speedpot.
* Settings will differ when using various options, such as using the -5 or the -7 option.
For the -17B option, Accel/Decel is 20 seconds when pot is turned fully clockwise.
* This trimpot chart is approximate. Use it in conjunction with the Adjustment Procedures.

TWO SPEED OPERATION

Two pot operation is done using two 10K
ohm speed potentiometers in parallel (both
HI's to P1-3, both LO's to P1-1). The
WIPER is switched using a SPDT switch.

DYNAMIC BRAKING

A DPDT switch is used to inhibit the control and to connect the
DBR. Typical values for the DBR (dynamic brake resistor) are 5
ohms for 120V, 10 ohms for 240V (both 35W to 50W). Note that
motor horsepower, inertia, and cycle time effect sizing of the DBR.
NOTE: This modification cannot be used with the -17B option.
