7.4.3 Parameter Numbers During Initial Parameter Error
<Parameter error No.>
f an initial parameter error (alarm 37) or set parameter warning (warning E4) occurs, the axis name and the No. of the
error parameter that exceeds the setting range will appear on the NC Diagnosis screen as shown below:
S02 Initial parameter error
S52 Parameter error warning ○○○○□
If an error No. in the following table is displayed as the error parameter No. even when the parameter is set to a value
within the setting range, an error is occurring due to the hardware compatibility or specifications or in relation to several
other parameters. Check the specifications and initial setup method of the direct-drive motor system, and correctly set
the parameters according to the descriptions in the following table.
Error parameter
No.
The parameter for enabling the absolute position control (#2049 type) is set before the initial setup is
2454
completed when MBA405W is connected.
The motor selected is of a motor series different from the drive unit's input voltage (200V/400V).
2217
Or a motor of an incompatible motor series is selected.
-In a semi-closed loop control system, the setting value of SV019 is different from that of SV020. Set them
2219
to the same value.
-SV019 is set to a value outside the setting range.
-The resolution of the motor side encoder actually connected is not consistent with the setting value for
2220
SV020.
-SV020 is set to a value outside the setting range.
Incompatible motor type is selected. The machine side encoder type or the motor side encoder type is
2225
incorrectly set.
2228
The magnetic pole shift amount (SV028) is set for a general servo motor (not a built-in motor).
The DC excitation mode (SV034/bit4) is set in the following conditions:
2234
-when the NC is powered ON
-when a general servo motor (not a built-in motor) is used.
When the DC excitation mode (SV034/bit4) is set, the initial DC excitation level (SV061) is set to a value
2261
outside the setting range.
When the DC excitation mode (SV034/bit4) is set, the final DC excitation level (SV062) is set to a value
2262
outside the setting range.
When the DC excitation mode (SV034/bit4) is set, the initial DC excitation time (SV063) is set to a value
2263
outside the setting range.
-The expansion sub side encoder resolution (SV117) is set to "0" for an encoder that requires the resolution
expansion setting.
2317
If the upper 16 bits for the encoder resolution are 0, this should be set to "-1".
-The expansion sub side encoder resolution (SV117) is set to a value other than "0" for an encoder that does
not support the resolution expansion setting.
-The expansion main side encoder resolution (SV118) is set to "0" for an encoder that requires the resolution
expansion setting.
2318
If the upper 16 bits for the encoder resolution are 0, this should be set to "-1".
-The expansion main side encoder resolution (SV118) is set to a value other than "0" for an encoder that
does not support the resolution expansion setting.
2321
Magnetic pole detection position loop gain (SV121) is not set at initial setup when MBA405W is connected.
2322
Magnetic pole detection speed loop gain (SV122) is not set at initial setup when MBA405W is connected.
Magnetic pole detection speed loop lead compensation (SV123) is not set at initial setup when MBA405W is
2323
connected.
