Block Title Parameter Description
MISCELLANEOUS
Continued Factory Settings Restores factory settings for all parameter values.
NO Does not change parameter values.
Select STD Settings and press “ENTER” key to restore standard 60Hz factory parameter
values. The keypad Display will show “Operation Done” then “NO” when completed.
Select 50Hz / 400Hz and press “ENTER” key to restore factory parameter values if using
a motor with a base frequency of 50Hz.
STAB Cutoff Freq The maximum range of adjustment at low output frequency and light load conditions to
eliminate instability. Factory setting is good for most applications.
Stability Gain The response time if instability occurs. Factory setting is good for most applications.
SECURITY
CONTROL Security State Off - No security access code required to change parameter values.
Local Security - Requires security access code to be entered before changes can be made
using the Keypad.
Serial Security - Requires security access code to be entered before changes can be made
using the RS232/422/485 link.
Total Security - Requires security access code to be entered before 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 settings but you are not allowed to change them 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 Display etc.).
Access Code A 4 digit code. You must know know this code to change secured Level 1 and Level 2
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 located on the lower right side of the Keypad
Display at the Enter Code prompt.
MOTOR DATA Motor Voltage The rated voltage of the motor (listed on the motor Nameplate). The value of this parameter
has no effect on the output voltage to the motor.
Motor Rated
Amps The rated current of the motor (listed on the motor Nameplate). If the motor current exceeds
this value for a period of time, an Overcurrent fault will occur. If multiple motors are used on
one control, add the Motor Rated Amps for all motors and enter this value.
Motor Rated
Speed 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 850 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. If multiple motors are used on one control, add the Motor Mag Amps for all
motors and enter this value.
BRAKE ADJUST Resistor Ohms The dynamic braking resistor value in ohms. Refer to MN701 (dynamic braking manual) or
call Baldor for additional information. If dynamic braking is not installed, enter zero.
Resistor Watts The dynamic braking resistor watts rating. Refer to dynamic braking manual or call Baldor
for additional information. If dynamic braking is not installed, enter zero.
DC Brake
Voltage The amount of DC braking voltage applied to the motor windings during a stop command.
Increase this value for more braking torque during stops. The increased braking voltage
may cause the motor to overheat for applications that require frequent starts/stops. Be
careful in selecting this value.
The maximum DC Brake Voltage = (1.414)X(Max Output Volts).
Max Output Volts is a Level 1 V/HZ and Boost parameter value.
DC Brake FREQ The output frequency (to the motor) at which dc injection braking will begin.
Brake on Stop If set to ON, DC injection braking will begin when a stop command is issued. After a stop
command, the DC brake voltage will be applied to the motor windings when the output
frequency reaches the DC brake frequency.
Brake on
Reverse If set to ON, DC injection braking will begin after a change-motor-rotation command is issued.
After a stop command, the DC brake voltage will be applied to the motor windings when the
output frequency reaches the DC brake frequency. Braking continues until the motor is
stopped. The motor will then accelerate in the opposite direction.
