Parameter

Description

 

 

 

SECURITY

Security State

Off - No security Access Code required to change parameter values.

CONTROL

 

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.
