5.7.4 Speed Agree
The IMPULSE
®
•G+ and VG+ Series 4 utilizes three different functions for detecting output frequency:
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.
When Frequency Detect is enabled using MFDO "H02-xx = 5":
• Contact opens at start.
• Contact closes when accelerating: U01-02 ≥ L04-01.
• Contact opens again when decelerating: U01-02 < (L04-01 - L04-02).
NOTE: If L04-01 or L04-03 is set below 5 Hz, the DC Injection Start Frequency (D01-01) and Speed Agree Widths
(L04-02/L04-04) may need to be adjusted lower in order for the VFD to recognize runs properly.
L03-23 CHP Stall P Sel This function reduces the Stall Prevention during run
level in the constant power range. (G+ only)
0, 1 0
0 Lvl set in L3-06 Sets the Stall Prevention level that is used throughout
the entire frequency range.
1 Autom. Reduction Automatic Stall Prevention level reduction in the
constant output range. The lower limit value is 40% of
L03-06.
L03-24 Mtr Accel Time Sets the time needed to accelerate the uncoupled
motor at rated torque from stop to the maximum
frequency.
