n H3-10: Terminal A2 Function Selection
Determines the function assigned to analog input terminal A2.
No.
H3-10
n Multi-Function Analog Input Terminal Settings
See Table 4.38 for information on how H3-02 and H3-10 determine functions for terminals A1 and A2.
Note: The scaling of all input functions depends on the gain and bias settings for the analog inputs. Set these to appropriate values when selecting
and adjusting analog input functions.
Setting
0 Frequency Bias
1 Frequency Gain
2 Auxiliary Frequency Reference 1
3 Auxiliary Frequency Reference 2
4 Output Voltage Bias
5 Accel/Decel Time Gain
6 DC Injection Braking Current
7 Overtorque/Undertorque Detection Level
8 Stall Prevention Level During Run
Setting 0: Frequency Bias
The input value of an analog input set to this function will be added to the analog frequency reference value. When the frequency
reference is supplied by a different source other than the analog inputs, this function will have no effect. Use this setting also
when only one of the analog inputs is used to supply the frequency reference.
By default, analog inputs A1 and A2 are set for this function. Simultaneously using A1 and A2 increases the frequency reference
by the total of all inputs.
Example: If the analog frequency reference from analog input terminal A1 is 50% and a bias of 20% is applied by analog input
terminal A2, the resulting frequency reference will be 70% of the maximum output frequency.
Setting 1: Frequency Gain
The input value of an analog input set to this function will be multiplied with the analog frequency reference value.
Example: If the analog frequency reference from analog input terminal A1 is 80% and a gain of 50% is applied from analog
input terminal A2, the resulting frequency reference will be 40% of the maximum output frequency.
Setting 2: Auxiliary Reference 1
Sets the auxiliary frequency reference 1 when multi-step speed operation is selected.
page 165 for details.
Setting 3: Auxiliary Reference 2
Sets the auxiliary frequency reference 2 when multi-step speed operation is selected.
page 165 for details.
Setting B: PI Feedback
Supplies the PI feedback value. This setting requires PI operation to be enabled in b5-01.
Setting C: PI Setpoint
Supplies the PI setpoint value and makes the frequency reference selected in parameter b1-01 no longer the PI setpoint. PI
operation to be enabled in b5-01 to use this setting.
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
In addition to motor overload fault detection oL1, it is possible to use a PTC (Positive Temperature Coefficient) thermistor
for motor insulation protection.
