Baldor 15H 用户手册

General Information 2-1

MN715

The Baldor Series 15H control is a PWM inverter motor control.  The control converts AC
line power to fixed DC power.  The DC power is then pulse width modulated into
synthesized three-phase AC line voltage for the motor.  In this way, the control converts
the fixed input frequency to variable output frequency to cause the motor to have variable
speed operation.

The rated horsepower of the control is based on a NEMA design B four pole motor and
60Hz operation at nominal rated input voltage. If any other type of motor is used, or input
voltage other than 230, 460 or 575 VAC is applied to the input terminals, the control
should be sized to the motor using the rated current of the motor.

The Baldor Series 15H control may be used in many different applications.  It may be
programmed by the user to operate in four different operating zones; standard constant
torque, standard variable torque, quiet constant torque or quiet variable torque.   It can
also be configured to function in a number of operating modes for custom operation.

It is the responsibility of the user to determine the optimum operating zone and operating
mode for the application.  These choices are programmed using the keypad as explained
in the programming section of this manual.

A custom unit may be required, contact Baldor.  Compliance to Directive 89/336/EEC is
the responsibility of the system integrator.  A control, motor and all system components
must have proper shielding grounding and filtering as described in MN1383.  Please refer
to MN1383 for installation techniques for CE compliance.
