YASKAWA TOEPYAIGA5002A GA500 DRIVE PROGRAMMING
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the time constant to adjust the acceleration rate when L3-01 = 3 [Stall Prevention during Accel
= Current Limit Acceleration]. Usually it is not necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the function to enable and disable the best S-curve characteristic used for current-limited
acceleration.
0 : Disabled
1 : Enabled
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the level to detect speed agree or motor speed.
Sets the level to detect speed agree or motor speed when H2-01 to H2-03 = 2, 3, 4, 5 [MFDO
Function Selection = Speed Agree 1, User-set Speed Agree 1, Frequency Detection 1, Frequency
Detection 2].
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the width to detect speed agree or motor speed.
Sets the width to detect speed agree or motor speed when H2-01 to H2-03 = 2, 3, 4, 5 [MFDO
Function Selection = Speed Agree 1, User-set Speed Agree 1, Frequency Detection 1, Frequency
Detection 2].
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the level to detect speed agree or motor speed.
Sets the level to detect speed agree or motor speed when H2-01 to H2-03 = 13, 14, 15, 16 [MFDO
Function Selection = Speed Agree 2, User-set Speed Agree 2, Frequency Detection 3, Frequency
Detection 4].
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the width to detect speed agree or motor speed.
Sets the width to detect speed agree or motor speed when H2-01 to H2-03 = 13, 14, 15, 16 [MFDO
Function Selection = Speed Agree 2, User-set Speed Agree 2, Frequency Detection 3, Frequency
Detection 4].
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the operation when the drive detects a loss of frequency reference.
0 : Stop
1 : Run at (L4-06 x Last Reference)
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the frequency reference as a percentage to continue drive operation after it detects a frequency
reference loss. The value is a percentage of the frequency reference before the drive detected the loss.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the condition that activates speed detection.
0 : No Detection during Baseblock
1 : Detection Always Enabled
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the drive to use the soft starter output frequency or the motor speed (estimation value) for speed
detection.
0 : Softstarter Output (Reference)
1 : Motor Speed (Actual Speed)
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the number of times that the drive will try to restart.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the function that sends signals to the MFDO terminal set for Fault [H2-xx = E] while the drive
is automatically restarting.
0 : Active Only when Not Restarting
1 : Always Active
