YASKAWA TOEPYAIGA5001A GA500 DRIVE MAINTENANCE & TROUBLESHOOTING
Sets the drive response to PID feedback loss/excess. Sets drive operation after the drive detects PID
feedback loss/excess.
0 : Digital Out Only, Always Detect
1 : Alarm + Digital Out, Always Det
2 : Fault + Digital Out, Always Det
3 : Digital Out Only, @ PID Enable
4 : Alarm + Digital Out, @PID Enable
5 : Fault + Digital Out, @PID Enable
Sets the level that triggers PID Feedback Loss [FbL] detection as a percentage of the Maximum
Output Frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]
Sets the length of time that PID Feedback must be less than b5-13 [PID Feedback Loss Detection
Lvl] to detect PID Feedback Loss [FbL].
Sets the output level that triggers the PID Sleep function.
Sets a delay time to start or stop the PID Sleep function.
Raises or lowers the PID setpoint using the acceleration and deceleration times set to the drive. This
is a soft-starter for the PID setpoint.
0 : Disabled
1 : Enabled
Sets the PID setpoint when b5-18 = 1 [b5-19 PID Setpoint Selection = Enabled].
Sets the number of digits to set and show the PID setpoint.
0 : 0.01Hz units
1 : 0.01% units
2 : rev/min
3 : User Units
Sets the lower limit level for the PID control as a percentage of E1-04 [Maximum Output
Frequency].
When you use b5-34, set b5-91 = 0 [EZ Sleep Minimum Speed = 0 (Disabled)].
When you set the output lower limit level as Hz units or min
reference ID.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]
Sets the output upper limit for the PID control as a percentage of the Maximum Output Frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]
Sets the level that triggers Excessive PID Feedback [FbH] as a percentage of the Maximum Output
Frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]
Sets the length of time that the PID feedback signal must be more than the level set in b5-36 [PID
Feedback High Detection Lvl] to cause Excessive PID Feedback [FbH].
Sets the value that the drive sets or shows as the PID setpoint when at the maximum output
frequency.
