P39 SPEED SCALING
This scales the display to indicate speed or user units other than frequency . This parameter
should be set to the desired display value when the drive output is 60 Hz . The highest setting
is 6500, and the highest value that can be displayed is 6553 .6 .
Example: A machine produces 175 parts per hour when the motor is running at 60 Hz .
Setting the SPEED SCALING to 175 will calibrate the drive's display to read 175 when the
motor is running at 60 Hz . This is a linear function, so at 30 Hz the display would read 87 .5,
and at 120 Hz, the display would read 350 .v
NOTE
If SPEED SCALING is set such that the maximum displayed value (6553 .6)
is exceeded, the display will flash "9999" to indicate that the value is out of
range . For example, if SPEED SCALING is set to 6000, the drive will display
6000 when it is running at 60 Hz . If the speed is increased past 65 .5 Hz
(at 65 .5 Hz, the scaled value would be 6550), the display will flash "9999"
because a scaled value above 6553 .6 cannot be displayed .
P40 FREQUENCY SCALING
This scales the analog output signal at TB-30 when it is configured for a frequency output .
This setting is the output frequency that is indicated when the output signal measures 10
VDC .
Example: A 0-5 VDC signal is required to indicate 0-60 Hz . Setting this parameter to 120 Hz
would yield 10 VDC at 120 Hz, and 5 VDC at 60 Hz . If the drive only operates up to 60 Hz,
the output signal at TB-30 is limited to the desired 0-5 VDC .
P41
LOAD SCALING
This scales the analog output signal at TB-30 when it is configured for a load output . This
setting is the load (in %) that is indicated when the output signal measures 10 VDC .
Example: A 0-10 VDC signal is required to indicate 0-150% load . Setting this parameter to
150% will yield 10 VDC at 150% load .
P42
ACCEL/DECEL #2
This parameter sets the second acceleration and deceleration rate of the drive . To activate
this acceleration and deceleration rate, use terminals TB-13A, TB-13B, TB-13C, or TB-13D .
TB-13A, TB-13B and TB-13D can be set to AUXILIARY STOP which will cause the drive to
decelerate to a stop according to the time programmed in this parameter . TB-13A, TB-13C
and TB-13D can be set to ACCEL/DECEL #2 which causes the drive to accelerate and
decelerate according to the time programmed in this parameter .
P43
SERIAL ADDRESS
If a serial link is being used to communicate with multiple drives, each drive must be given a
different address (from 1 to 247) so that an individual drive in the network can be accessed .
