7.3.4 Parameter Numbers during Initial Parameter Error

If 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 of the servo and spindle system and the descriptions in the following table to
correctly set the parameters.
(1) Servo parameter error No.
Error parameter
No.
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
incorrectly set.
For the speed command synchronous control system with MDS-E/EH-V2/V3,
-The L axis for the drive unit is set as the secondary axis. Set the M axis as the secondary axis.
-The motor side encoders for the L axis and the M axis are different. Use encoders of the same specifications.
For the distance-coded reference scale system,
2225
-When a HEIDENHAIN serial conversion interface unit is connected, the encoder type setting is different from
the connected unit type.
-When a HEIDENHAIN serial conversion interface unit with the rotary type is connected, the ball screw pitch
(SV018) is set to a value other than "360".
-The speed command synchronous control and the distance-coded reference scale connection are set
concurrently.
2228 The magnetic pole shift amount (SV028) is set for a general servo motor (not a built-in motor).
The vertical axis pull up function (SV033/bitE) is set in the following conditions:
-when the vertical axis pull up direction is not set (SV032=0)
-when the drop prevention function is not set (SV048=0)
2233
The vertical axis pull up function (SV033/bitE) is not set in the following condition:
-when the vertical axis pull up distance is set (SV095 ≠ 0)
Parallel connection is set when the motor is not a linear servo motor.
Or 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.
