2.8 H: Terminal Function Selection
340 YASKAWA TOEPYAIGA5002A GA500 DRIVE PROGRAMMING
■ 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 = 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 (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.
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.
