Bias and Gain Settings
Important: The maximum allowable drive output frequency will be
determined by the lowest programmed value of any of the following
parameters:
•
Parameter 3 Frequency Range
•
Parameter 15 Maximum Frequency
•
Parameter 51 Upper Frequency Clamp
•
Parameter 53 Bias Frequency –– If Parameter 53 is Higher Than
Parameter 54
•
Parameter 54 Gain Frequency –– If Parameter 54 is Higher Than
Parameter 53
Parameter 52 -- Bias and Gain Enable
Units = Code
Range = 0/1
Factory Setting = 0
This parameter enables or disables both the Bias and Gain Frequencies set
by Parameters 53 and 54. Bias and Gain Frequencies allows a remote speed
signal to be used within a specific minimum and maximum frequency
range. The Bias and Gain Frequencies may be used to provide a directly or
inversely proportional 0-5V DC, 0-10V DC, 4-20 mA, or external speed
pot signal at the Control and Signal Wiring Terminal Block.
If set to 0, the bias and gain function is disabled.
If set to 1, the bias and gain function is enabled.
If the 1333 is to produce 0 output speed at 0 external input signal:
•
Parameter 9 Local/Remote Frequency must be set to remote.
•
Parameter 52 Bias and Gain Enabled must be enabled.
•
Parameter 53 Bias Frequency must be set to the minimum output
frequency required.
•
Parameter 54 Gain Frequency must be set to the maximum output
frequency required.
If the 1333 is to produce maximum output speed at 0 external input signal:
•
Parameter 9 Local/Remote Frequency must be set to remote.
•
Parameter 52 Bias and Gain Enabled must be enabled.
•
Parameter 53 Bias Frequency must be set to the maximum output
frequency required.
•
Parameter 54 Gain Frequency must be set to the minimum output
frequency required.
