Gain
This parameter provides a degree of slip compensation for a given load. A
higher setting here decreases the slip allowed for a given load/ASD output ratio.
Parameter Type — Numerical

VI/II Speed Frequency Setpoint #1
Program ⇒ Frequency Settings ⇒ Speed Reference Setpoints ⇒ VI/II
⇒ VI/II Speed Frequency Setpoint #1
This parameter is used to set the gain and bias of the VI/II input terminal when
the VI/II terminal is used as the control input while operating in the Speed
Control mode.
Note: See note on pg. 33 for further information on the VI/II
terminal.
VI/II Input Speed Control Setup
Perform the following setup to allow the system to receive Speed control input
at the VI/II input terminal:
• Program ⇒ Utilities ⇒ Command and Frequency Settings ⇒ Command
Mode Select ⇒ Terminal Block.
• Program
⇒ Utilities ⇒ Command and Frequency Settings ⇒ Frequency#1
Mode Select ⇒ VI/II.
• Provide a Run command (F and/or R).
Speed Control
Perform the following setup to allow the system to perform Speed control from
the VI/II input terminal:
• Set VI/II Speed Frequency #1,
• Set the VI/II input signal level (VI/II Speed Ref #1) that represents VI/II
Speed Frequency #1,
• Set VI/II Speed Frequency Setpoint #2 , and
• Set the VI/II input signal level (VI/II Speed Ref #2) that represents VI/II
Speed Frequency Setpoint #2 .
Once set, as the VI input voltage or the II current changes, the output frequency
of the ASD will vary in accordance with the above settings.
This parameter sets VI/II Speed Frequency #1 and is the frequency that is
associated with the setting of
VI/II Speed Reference Setpoint #1 when
operating in the Speed Control mode.
