RS485 Master Output
Program
⇒
Comm Settings
⇒
RS485 Master Out
In a master/follower configuration, this setting determines the output parameter
of the master ASD that will be used to control the applicable follower ASDs.
Note: Select Normal if TTL Master Out is configured as a Master
Output controller. Otherwise, a keypad failure will result.
Changes made to this parameter require that the power be cycled (Off then On)
for the changes to take effect.
Settings:
Normal (No Slave)

Parameter Type — Selection List
Factory Default — Normal (No Slave)
Changeable During Run — Yes
RS485 Response Time

⇒
Comm Settings
⇒
RS485 Res Time
This parameter sets the RS232/485 response delay time.
Changes made to this parameter require that the power be cycled (Off then On)
for the changes to take effect.
Parameter Type — Numerical
Factory Default — 0.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — 2.00
Units — Seconds
RS485 Wire Count
Program
⇒
Comm Settings
⇒
RS485 Wire Count
This parameter sets the communications protocol to the 2 or 4 wire method.
Changes made to this parameter require that the power be cycled (Off then On)
for the changes to take effect.
Settings:
2 wire
4 wire
Parameter Type — Selection List
Factory Default — 4-Wire
Changeable During Run — Yes
Run Frequency
Program
⇒
Special Controls
⇒
Run Frequency
This parameter establishes a center frequency (Run Frequency) of a frequency
band.
The Run Frequency Hysteresis
parameter provides a plus-or-minus value for
the Run Frequency; thus, establishing a frequency band.
During acceleration, the ASD will not output a signal to the motor until the
lower level of the band is reached.
During deceleration, the ASD will continue to output the programmed
deceleration output signal to the motor until the lower level of the band is
reached; at which time the output will go to 0.0 Hz.
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — Yes
Minimum — 0.0
Maximum — Max. Freq.
Units — Hz
