Figure 41 - One External Motor without AutoSwap
• Auxiliary Motor Control is enabled via Parameter R239 [Aux Motor
Mode].
• Number of auxiliary motors is set via Parameter R240
[Aux Motor Qty].
• Relays are configured for Auxiliary Motor Control via parameters T055
,
T060
, R222, and R225.
• The frequency of Motor #1 that Motor #2 turns on at is set via
Parameter R241
[Aux 1 Start Freq].
• The time that Motor #1 is above the value set by R241
[Aux 1 Start
Freq] before turning on Motor #2 is set via Parameter R250
[Aux Start
Delay].
• The frequency of Motor #1 that Motor #2 turns off at is set via
Parameter R242
[Aux 1 Stop Freq].
• The time that Motor #1 is below the value set by R242
[Aux 1 Stop
Freq] before turning off Motor #2 is set via Parameter R251
[Aux Stop
Delay].
• PID setup is done via Parameters A150
through A159. See Appendix D
for additional information.
