Setting F: Not Used
Any analog input that is not used should be set to F. When set to "F", an input does not affect any drive function but the input
level can be read out by a PLC via a communication option or MEMOBUS/Modbus communications (through mode). This
way drive analog inputs can be used to read out external sensor values if there is a lack of PLC analog inputs.
Setting 10/11/12/15: Positive/Negative/Regenerative/General Torque Limit (OLV only)
These functions make it possible to limit the torque reference with an analog input. The limit can either be set as a general
value for all operation conditions (setting 15) or can be programmed separately for each operation condition (quadrants 1, 2,
3, and 4). Figure 5.73 shows which limit is applied in each quadrant. The lowest of the values will always be used as the limit.
The value is set as a percentage of the motor rated torque.

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.

Setting 30/31: DriveWorksEZ Analog Input 1/2
These settings are for analog output functions used in DriveWorksEZ. Normally there is no need to change or apply these
settings.
Setting 41: Output Voltage Gain
Allows the user to change the output voltage by adjusting the voltage reference via one of the analog input terminals or with
MEMOBUS/Modbus.
An internal 0.3 second delay has been added to prevent sudden, drastic change to the V/f pattern.
Note: When an input terminal is assigned to adjust the Output Voltage Gain (H3-oo = 41), a voltage reference from MEMOBUS/Modbus is
ignored.
n H3-14: Analog Input Terminal Enable Selection
Note: Parameter available in drive software versions PRG: 1016 and later.
Determines which of the analog input terminals will be enabled or disabled when a digital input programmed for "Analog
input enable" (H1-oo = C) is closed. When H1-oo ≠ C, all of the input terminals are enabled all of the time. Terminals not
set as the target are not influenced by input signals.
No.

Setting 1: Terminal A1 only
Setting 2: Terminal A2 only
Setting 7: All Terminals Enabled
n
H3-16/H3-17: Terminal A1/A2 Offset
Note: Parameters available in drive software versions PRG: 1016 and later.
Determines the amount of offset to be used to calibrate analog input signals from the terminals A1 and A2.
