Setup
This group contains parameters that are required to setup advanced functions of the drive
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 cannot be changed while the drive is running.
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 cod-
ed PWM output waveform.
This parameter cannot be changed while the drive is running.
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 A & B Frame Drives = 8 kHz
C Frame Drives & Up = 6 kHz
[Accel Time 2]
This value determines the time it will take the drive to ramp
from 0 Hz to [Maximum Freq]. The rate determined by this
value and [Maximum Freq] is linear unless [S Curve En-
able] is “Enabled.” It applies to any increase in command
frequency unless [Accel Time 1] is selected.
Parameter Number 30
Parameter Type Read and Write
Display Units / Drive Units 0.1 Second / Seconds x 10
Factory Default 10.0 Sec
Minimum Value 0.0 Sec
Maximum Value 3600.0 Sec
[Decel Time 2]
This value determines the time it will take the drive to ramp
from [Maximum Freq] to 0 Hz. The rate determined by this
value and [Maximum Freq] is linear unless [S Curve En-
able] is “Enabled.” It applies to any decrease in command
frequency unless [Decel Time 1] is selected.
Parameter Number 31
Parameter Type Read and Write
Display Units / Drive Units 0.1 Second / Seconds x 10
Factory Default 10.0 Sec
Minimum Value 0.0 Sec
Maximum Value 3600.0 Sec

Speed Sync Bit
Important: The accel/decel/s-curve control is active during speed sync and will limit the rate of change of
frequency if set “slower.”
Synchronized Speed Change Function
This function is typically used in an application where multiple 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: [TB3 Term 22 Sel] = “Sync”
Important: Do not select more than one input terminal as the SYNC 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”.
