Block Title Parameter Description
SECURITY
CONTROL
Security State Off - No security Access Code required to change parameter values.
Local - Requires security Access Code to be entered (using the keypad) before
parameter changes can be made using the Keypad.
Serial - Requires security Access Code to be entered (over the Serial Link) before
parameter changes can be made using the Serial Link.
Total - Requires security Access Code to be entered (using Keypad or Serial Link)
before parameter changes can be made using the Keypad or serial link.
Note: If security is set to Local, Serial or Total you can press PROG and scroll
through the parameter values and view their values but you are not allowed
to change their values unless you enter the correct access code.
Access Timeout The time in seconds the security access remains enabled after leaving the programming
mode. If you exit and go back into the program Mode within this time limit, the
security Access Code does not have to be re-entered. This timer starts when leaving
the Program Mode (by pressing DISP).
Note: This feature is not available when using the Serial operating mode or if
power is cycled.
Access Code A 4 digit number code. Only persons that know the code can change secured Level 1
and Level 2 parameter values.
Note: Please record your access code and store it in a safe place. If you cannot
gain entry into parameter values to change a protected parameter, please
contact Baldor. Be prepared to give the 5 digit code shown on the lower
right side of the Keypad Display at the Security Control Access Code
parameter prompt.
MOTOR DATA Motor Voltage The rated voltage of the motor (listed on the motor nameplate).
Motor Rated Amps The full load current of the motor (listed on the motor nameplate). If the motor current
exceeds this value for a period of time, an Overload fault will occur.
Motor Rated SPD The rated speed of the motor (listed on the motor nameplate). If Motor Rated SPD =
1750 RPM and Motor Rated Freq = 60 Hz, the Keypad Display will show 1750 RPM
at 60 Hz and 875 RPM at 30Hz.
Motor Rated Freq The rated frequency of the motor (listed on the motor nameplate).
Motor Mag Amps The motor magnetizing current value (listed on the motor nameplate). Also called no
load current. Measure using a clamp on amp meter at the AC power line while the
motor is running at line frequency with no load connected to the motor shaft.
Encoder Counts The number of encoder feedback counts (lines per revolution).
Resolver Speed The speed of the resolver, if a resolver is used for feedback.
CALC Presets This procedure loads preset values into memory that are required to perform Auto Tune.
Always run CALC Presets as the first step of Auto Tune.
