5.7.4 Reference Detection
Speed Agree 1
• When enabled using MFDO “H02.xx = 2", the contact closes when the output frequency (U01.02) is equal to
the frequency reference (U01.01) plus or minus the speed agree detection width (L04.02).
• U01.02 = (U01.01 ± L04.02)
• When enabled using MFDO “H02.xx = 3”, the contact closes when the output frequency (U01.02) is equal to
the speed agree detection level (L04.01) plus or minus the speed agree detection width (L04.02).
• U01.02 = (L04.01 ± L04.02)
Speed Agree 2
• When enabled using MFDO “H02.xx = 13”, the contact closes when the output frequency (U01.02) is equal to
the frequency reference (U01.01) plus or minus the speed agree detection width (L04.04).
• U01.02 = (U01.01 ± L04.04)
• When enabled using MFDO “H02.xx = 14”, the contact closes when output frequency (U01.02) is equal to the
speed agree detection level (L04.03) plus or minus the speed agree detection width (L04.04).
• U01.02 = (L04.03 ± L04.04)
Frequency Detect
When Frequency Detect is enabled using MFDO “H02.xx = 4":
• Contact closes at start.
• Contact opens when accelerating: U01.02 ≥ (L04.01 + L04.02).
• Contact closes again when decelerating: U01.02 < L04.01.
Parameter Name Function Range Default
L03.17 Overvoltage Suppression and
Stall Prevention Sets the desired value for the DC bus voltage
during overvoltage suppression and Stall
Prevention during deceleration. 150–400 VDC 370
L03.23 Automatic Reduction Selection
for Stall Prevention during Run Automatic Reduction Selection for Stall
Prevention during Run 00, 01 00
00 Sets the Stall Prevention level throughout the entire frequency range
to the value in parameter L03.06
01 Automatically lowers the Stall Prevention level in the constant output
range. The lower limit value is 40% of L03.06
L03.24 Motor Acceleration Time for
Inertia Calculations Sets the time needed to accelerate the
uncoupled motor at rated torque from stop to
the maximum frequency. Setting the VFD
capacity to parameter O02.04 or changing
E02.11 will automatically set this parameter
for a 4-pole motor. 0.001–10.000
sec
Depends
on
O02.04
L03.25 Load Inertia Ratio Sets the ratio between the connected
machinery and the motor 0.0–1000.0 1.0
