RR Speed Frequency Setpoint #1
Program ⇒ Frequency Settings ⇒ RR ⇒ RR Speed Frequency
Setpoint #1
This parameter is used to set the gain and bias of the RR input terminal when
the RR terminal is used as the control input while operating in the Speed
Control mode.
RR Input Speed Control Setup
Perform the following setup to allow the system to receive Speed control input
at the RR input terminal:
• Program
⇒ Utilitites ⇒ Command and Frequency Settings ⇒ Frequency
Mode#1 Select
⇒ RR.
• Program ⇒ Utilitites ⇒ Command and Frequency Settings ⇒ Command
Mode Select ⇒ (any setting).
• Provide a Run command (F and/or R).
Speed Control
Perform the following setup to allow the system to perform Speed control from
the RR input terminal:
• Set RR Speed Frequency #1,
• Set the RR input signal level (RR Speed Ref #1) that represents RR Speed
Frequency #1,
• Set RR Speed Frequency #2, and
• Set the RR input signal level (RR Speed Ref #2) that represents RR Speed
Frequency #2.
Once set, as the RR input voltage changes the output frequency of the ASD will
vary in accordance with the above settings.
This parameter sets RR Speed Frequency #1 and is the frequency that is
associated with the setting of RR Speed Reference #1 when operating in the
Speed Control mode.

RR Speed Frequency Setpoint #2
Program ⇒ Frequency Settings ⇒ RR ⇒ RR Speed Frequency
Setpoint #2
This parameter is used to set the gain and bias of the RR input terminal when
the RR terminal is used as the control input while operating in the Speed
Control mode.
See RR Speed Frequency #1 for further information on this setting.
This parameter sets RR Speed Frequency #2 and is the frequency that is
associated with the setting of RR Speed Reference #2 when operating in the
Speed Control mode.
