When you use this function, set b5-01 = 1 to 8 [PID Mode Setting = Enabled] .
■
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 = 1 to 8 [PID Mode Setting = Enabled] .
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 d1-16 or d1-17 [Reference 1 to 16 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 (PLC) 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.
•
If the drive detects oH3 , the motor stops with the method set in L1-03 . If the drive detects oH4 , the motor stops with
the method set in L1-04 . If 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.
When you set a terminal that is not in use to F, you can use the signal input to the terminal as PLC analog signal input
through MEMOBUS/Modbus communications or the communication option. This input signal does not have an effect
on drive operation. This functions the same as setting 1F (Through Mode).
■
10: Forward Torque Limit
Setting Value Function Description
10 Forward Torque Limit
Enters the forward torque limit if the motor rated torque is 100%.
WARNING! Sudden Movement Hazard. Set correct torque limits for applications, for example elevator applications. If you set torque
limits incorrectly, motor torque that is not sufficient can cause damage to equipment and cause serious injury or death.
Torque Limit Configuration Method
Use one of these methods to set torque limits:
•
Individually set the four torque limit quadrants using L7-01 to L7-04 [Torque Limit] .
•
Use MFAI to individually set the four torque limit quadrants. Set H3-02, H3-06, H3-10 = 10, 11, 12 [MFAI
Function Select = Forward/Reverse/Regenerative Torque Limit] .
• Use MFAI to set all four torque limit quadrants together. Set H3-02, H3-06, H3-10 = 15 [General Torque Limit] .
