This group containsparameters thatarerequired tosetupadvanced functionsof thedrive
for complex applications.
[Minimum Freq]
This parameter sets the lowest frequency the drive will
output.
Parameter Number 16
Parameter Type Read and Write
Display Units / Drive Units 1 Hertz / Hertz x 10
Factory Default 0 Hz
Minimum Value 0 Hz
Maximum Value 120 Hz
[Maximum Freq]
This parameter sets the highest frequency the drive will
output.
This parameter cannotbe changed whiledrive isrunning.
Parameter Number 19
Parameter Type Read and Write
Display Units / Drive Units 1 Hertz / Hertz x 10
Factory Default 60 Hz
Minimum Value 10 Hz
Maximum Value 400 Hz
[PWM Frequency]
This parameter sets the carrier frequency for the sine
coded PWM output waveform.
This parameter cannotbe changed whiledrive isrunning.
Refer to the Derating Guidelines in Appendix A.
Parameter Number 45
Parameter Type Read and Write
Display Units / Drive Units 2 KHz / KHz/2
Factory Default 2 KHz
Minimum Value 2 KHz
Maximum Value 240V AC Drives = 8 kHz
480V AC Drives = 4 kHz

Synchronized Speed Change Function
Thisfunction istypically usedin anapplication wheremultiple drives,drive
different functions on one machine and the line speed must be changed.
To initiate the speed sync function:
- The drive must be running.
- [Sync Time] must be set to a non-zero value.
- [Freq Source] must be set to “Adapter 1-6” or “Preset 1-7.”
- A SYNC input must be energized.
The SYNC input can come from any of the programmable input terminals.
Example: [TB5 Term 22 Sel] = “Sync”
Important: Do notselect more thanone input terminal as theSYNC input.
The sync input can also come through SCANport from one of the communication options, either as a “Type 1” or “Type 2” message. For further information,
refer to the instructions supplied with the option. Also, see the section titled “Communications Data Information Format” in Appendix A.
The usual sequence of events:
- Energize the SYNC input.
- The “Speed Sync” bit in [Application Sts] is set to “1”.
- The drive “holds” the last frequency reference value.
- The frequency command is changed and/or a different source is selected.
- De-energize the SYNC input.
- The drive will linearly ramp from the “held” reference to the new reference in a time set by [Sync Time].
- The “Speed Sync” bit in [Application Sts] is set to “0”.

Important: The accel/decel/s-curve control is active during speed sync and will limit the rate of change of
frequency if set “slower.”
