Setting 8: Stall Prevention Level During Run
This setting allows an analog input signal to adjust the Stall Prevention level. Figure 5.57 shows the setting
characteristics. The drive will use either the Stall Prevention level set to L3-06 or the level coming from the analog input
terminal that has been selected, whichever value is lower.

Setting 9: Output Frequency Lower Limit Level
The user can adjust the lower limit of the output frequency using an analog input signal.
Setting B: PI Feedback
An input set for this function supplies the PI feedback value. This setting requires PI operation to be enabled in b5-01.
Refer to PI Feedback Input Methods on page 146.
Setting C: PI Setpoint
An input set for this function supplies the PI setpoint value, and the frequency reference selected in parameter b1-01 is no
longer the PI setpoint. PI operation to be enabled in b5-01 to use this setting. Refer to PI Setpoint Input Methods on
page 146.
Setting D: Frequency Bias
The input value of an analog input set to this function will be added to the frequency reference. This function can be used
with any frequency reference source.
Setting E: Motor Temperature (PTC input: A3 only)
In addition to motor overload fault detection oL1, it is possible to use a PTC (Positive Temperature Coefficient)
thermistor for motor insulation protection. Connect the PTC to analog input terminal A3, and set switch S4 on the
terminal board to PTC. Refer to Terminal A3 Analog/PTC Input Selection on page 125 for details on setting S4. Refer to
Motor Protection Using a Positive Temperature Coefficient (PTC) on page 210 for further explanation.
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 16: Differential PI Feedback
If an analog value is set for this function, the PI controller is set for differential feedback. The subtraction of the PI
feedback input value and the differential feedback input value builds the feedback value that is used to calculate the PI
input. Refer to PI Feedback Input Methods on page 146.
Setting 17: Motor Thermistor (NTC)
Used as a complement or a substitution for oL1. Refer to Motor Protection Using an NTC Thermistor Input on
page 212.
Setting 30, 31, 32: DriveWorksEZ Analog Input 1, 2, 3
These settings are for functions used in DriveWorksEZ. Normally there is no need to change or apply these settings.
