Setting F, 1F: Through mode
When set to F or 1F, an input does not affect any drive function, but the input level can still be read out by a PLC via a
communication option or MEMOBUS/Modbus communications.
Setting 10, 11, 12, 15: Forward, Reverse, Regenerative, General torque limit (OLV, CLV, AOLV/PM, CLV/PM)
These functions can be used to set a torque limit using analog inputs for different operating conditions. Refer to
Setting 13: Torque Limit Using Torque Reference/Speed Limit
When using Torque Control, an analog input programmed to this function can set the torque reference (when in Torque
Control) or the torque limit (when in Speed Control). Refer to
Setting the Torque Reference, Speed Limit, and Torque
Compensation Values on page 158
for details.
Setting 14: Torque compensation
Used to set a torque compensation value when using Torque Control. Refer to
Setting the Torque Reference, Speed
Limit, and Torque Compensation Values on page 158
for details.
Setting 16: Differential PID Feedback
If an analog value is set for this function, the PID controller is set for differential feedback. The subtraction of the PID
feedback input value and the differential feedback input value builds the feedback value that is used to calculate the PID
input.
Refer to PID Feedback Input Methods on page 128
.
Setting 41: Output Voltage Gain
Adjust the output voltage gain using the analog input signal.
An input signal of 0 V or 4 mA equals 2% output voltage gain, and an input signal of 10 V or 20 mA equals 200% output
voltage gain.
Note:
MEMOBUS register 03H will be disabled if an input terminal has been set to determine the output voltage gain level (H3-
=
41).
Figure 5.72
Figure 5.72 Output Voltage Gain Using an Analog Input Terminal
When the output voltage gain function is disabled (S3-03 = 0), the output voltage will be 100%.
When the S3-03 = 1 (enabled), the output voltage gain will be affected in accordance with the output voltage gain time
setting in parameter S3-04.
Example of How to Set the Gain Level
When S3-04 = 0.5, changing the output voltage gain from 100% to 200% takes 0.5 s for the actual output voltage gain to
reach 200%.
