Operation Errors - YASKAWA Varispeed G7 Instruction Manual

Operation Errors

An operation error will occur if there is an invalid setting or a contradiction between two constant settings. It
won't be possible to start the Inverter until the constants have been set correctly. (The alarm output and fault
contact outputs will not operate either.)
When an operation error has occurred, refer to the following table to identify and correct the cause of the
errors.

Meaning
The Inverter capacity setting doesn't match the Unit. (Contact your Yaskawa repre-
sentative.)
The constant setting is outside of the valid setting range. Press the ENTER Key on
the Digital Operator to display OPE fault constant (U1-34).
One of the following errors has been made in the multi-function input (H1-01 to H1-
10) settings:
• The same setting has been selected for two or more multi-function inputs.
• An up or down command was selected independently. (They must be used
together.)
• The up/down commands (10 and 11) and Accel/Decel Ramp Hold (A) were
selected at the same time.
• Speed Search 1 (61, maximum output frequency) and Speed Search 2 (62. set fre-
quency) were selected at the same time.
• The up/down commands (10 and 11) were selected while PID Control Method
Selection (b5-01) was enabled.
• Positive and negative speed commands have not been set at the same time.
• The emergency Stop Command NO and NC have been set at the same time.
The option board was selected as the frequency reference source by setting b1-01 to
3, but an option board isn't connected (C option).
V/f control with PG feedback was selected by setting A1-02 to 1, but a PG Speed
Control Board isn't connected.
The same setting has been selected for the analog input selection and the PID func-
tion selection.
• H3-09 = B and H6-01 = 1
• H3-09 = C and H6-01 = 2
b1-01 (Reference Selection) is set to 4 (pulse input) and H6-01 (Pulse Train Input
Function Selection) is set to a value other than 0 (frequency reference).
A setting has been made that is not required in the current control method. Ex.: A
function used only with open-loop vector control was selected for V/f control. Press
the ENTER Key on the Digital Operator to display OPE fault constant (U1-34).
The following settings have been made at the same time.
• b5-01 (PID Control Method Selection) has been set to a value other than 0.
• b5-15 (PID Sleep Function Operation Level) has been set to a value other than 0.
• b1-03 (Stopping Method Selection) has been set to 2 or 3.
Constants E1-04, E1-06, E1-07, and E1-09 do not satisfy the following conditions:
• E1-04 (FMAX) ≥ E1-06 (FA) > E1-07 (FB) ≥ E1-09 (FMIN)
• E3-02 (FMAX) ≥ E3-04 (FA) > E3-05 (FB) ≥ E3-07 (FMIN)
