9: Output Frequency Lower Limit
Setting Value Function Description
9 Output Frequency Lower
Limit Enters a signal to adjust the output frequency lower limit level as a percentage of the maximum output frequency.
■
B: PID Feedback
Setting Value Function Description
B PID Feedback Enter the PID feedback value as a percentage of the maximum output frequency.
When you use this function, set b5-01 ≠ 0 [PID Mode Setting ≠ Disabled] .
■
C: PID Setpoint
Setting Value Function Description
C PID Setpoint Enters the PID setpoint as a percentage of the maximum output frequency.
When you use this function, set b5-01 ≠ 0 [PID Mode Setting ≠ Disabled] .
Note:
Configuring this function disables the frequency reference set with b1-01 [Frequency Reference Selection 1] .
■
D: Frequency Bias
Setting Value Function Description
D Frequency Bias Enters the bias value added to the frequency reference as a percentage of the maximum output frequency.
The drive adds the input value from the MFAI terminal set with this function to the frequency reference as the bias
value.
Note:
When you select d1-01 to d1-17 [Reference 1 to 8 or JOG Frequency Reference] as the frequency reference, it will disable this function.
■
E: Motor Temperature (PTC Input)
Setting Value Function Description
E Motor Temperature (PTC
Input) Uses the motor Positive Temperature Coefficient (PTC) thermistor to prevent heat damage to the motor as a percentage of the
current value when the 10 V analog signal is input.
•
You can use the Positive Temperature Coefficient (PTC) thermistor as an auxiliary or alternative detection function
for
oL1 [Motor Overload] problems to help prevent heat damage to motors. If the PTC input signal is more than the
overload alarm level, oH3 [Motor Overheat (PTC Input)] will flash on the keypad.
•
When the drive detects oH3 , the motor stops with the setting in L1-03 . When the drive detects oH4 , the motor stops
with the setting in L1-04 . When the drive incorrectly detects motor overheating problems, set L1-05 .
■
F: Not Used
Setting Value Function Description
F Not Used Use this setting for unused terminals or to use terminals in through mode.
