The analog input gain and bias for the frequency reference input are set incorrectly.
|
Examine the gain and bias settings for the analog inputs that set the frequency reference.
-
Terminal A1: H3-03 [Terminal A1 Gain Setting], H3-04 [Terminal A1 Bias Setting]
-
Terminal A2: H3-11 [Terminal A2 Gain Setting], H3-12 [Terminal A2 Bias Setting]
|
|
The drive is receiving frequency bias signals from analog input terminals A1 and A2 and the sum of all signals makes the frequency reference.
|
-
Examine parameters H3-02, H3-10 [MFAI Function Select]. If both of these parameters = 0, change the settings.
-
Use U1-13, U1-14 [Terminal A1, A2 Input Voltage] to make sure that the analog input values set to terminals A1 and A2 are applicable.

PID control is enabled.
|
If PID control is not necessary, set b5-01 = 0 [PID Mode Setting = Disabled].
Note:
When PID control is enabled, the drive adjusts the output frequency as specified by the target value. The drive will only accelerate to the maximum output frequency set in E1-04 [Maximum Output Frequency] while PID control is active.
