Note 3. When supplying a voltage input to the frequency reference current input (terminal 14), be sure
to disconnect jumper wire J1 on the control board. If the jumper wire isn’t disconnected, the
input resistor will be destroyed. Refer to page 6-22 for a diagram of the control board.

Adjusting the Gain/Bias of the Analog Inputs
•
Adjust the gain and bias for the frequency reference (voltage), frequency reference (current), and mul-
ti-function analog inputs according to the input specifications for each input. The following parameters
can be changed during operation.

Note 1. Adjust the gain so that the maximum signal level corresponds to the maximum frequency or
the motor’s rated torque, as follows.
When the input terminal is used for frequency reference:
A 10-V (20 mA) input indicates a frequency reference that is 100% of the max. frequency.
When the input terminal is used for torque reference:
A 10-V (20 mA) input indicates a torque reference that is 100% of the motor’s rated torque.
When the input terminal is used for torque compensation:
A 10-V (20 mA) input indicates a torque compensation that is 100% of the motor’s rated torque.
Note 2. Adjust the bias so that the minimum signal level corresponds to the maximum frequency or
the motor’s rated torque, as follows.
When the input terminal is used for frequency reference:
A 0-V (4 mA) input indicates a frequency reference that is 100% of the max. frequency.
When the input terminal is used for torque reference:
A 0-V (4 mA) input indicates a torque reference that is 100% of the motor’s rated torque.
