8. The motor will start with the default acceleration ramp time of 0-30 Hz in one second, then 30-60
Hz in ten seconds.
9. Confirm that the motor rotation is correct. Swapping any two of the output leads or using the
REVERSE ROTATION
parameter will reverse the motor rotation.
10. After initial power-up, use the keypad and display to navigate to
CHANGE PARAMETER VALUES
to set any other adjustable parameters you wish to be different from the factory defaults.

Motor Overload Protection
SD & 2XD Series drives are equipped with adjustable solid-state motor overload protection. Protection
is based on a Class 10 trip curve. Motor overload settings are selected by navigating to the appropriate
menu item using the keypad and display.
THERMAL MEMORY
is the ability of an overload protective system to approximate the heating cooling
of a protected motor during operation.
THERMAL MEMORY RETENTION
maintains the thermal memory upon shutdown or power loss. This
includes retention of the last thermal value and may include an ongoing reduction of this thermal value
to reflect the cooling of the motor. This information will be used by the overload protective system to
approximate the thermal state of the motor upon restart.
CAUTION
: Do not attempt to restart the motor immediately after a motor overload fault. The motor
overload protection system uses a timer to approximate motor cooling and may trigger an immediate
overload fault if the motor is restarted too soon.
Setting Motor Overload Protection with Keypad
To set motor overload protection with the keypad, navigate to the Main Menu item

System Configuration
SD/2XD Series drives are capable of operating several types of systems, including constant pressure
water systems, with simple ON/OFF control from remote switches.
The correct system configuration
must be selected for proper operation of different types of control systems.
