11.5 Bank Switching Function
11.5.4 Bank Member Setting
11-20
( 4 ) Precautions on Setting
• When the parameter Number of Banks (Pn900) or Number of Members (Pn901) is set to 0, the standard parame-
ters will be used so that the Bank Switching function is invalid.
• When the members registered in Parameter Bank Member Definition (Pn902 to Pn910) are overlapped, the bank
data of the member with the bigger Parameter Bank Member Definition number will be applied.
• The Number of Parameter Banks (Pn900), Number of Parameter Bank Members (Pn901), and Parameter Bank
Member Definition (Pn902 to Pn910) are offline parameters and these settings will be validated after turning
OFF the power and turning ON, or by executing CONFIG command.
• When the Machine Controller setting parameter Bank Selector (OW 04, bits C to F) is set to 0 (BANK_SEL
= 0), the bank data will be used. Set the Bank 0 to the default value.
• The Bank will be switched after pulse distribution is completed (DEN = 1). It will not be switched while pulse is
being distributed (DEN = 0).
• If the Parameter Bank Data (Pn920 to Pn95F) of the selected bank is changed while pulse is being distributed
(DEN = 0), the SERVOPACK will generate the warning A.95A and ignore the command.
• A.04A (Parameter Error) will occur after turning ON the power and then turning OFF, or after executing CON-
FIG command in the following cases.
• A parameter that is not applicable for bank member has been set.
• The bank data is out of the setting range.
• The total number of bank data exceeds 64 (Pn900
× Pn901 > 64)
• When both the Bank Switching function and other torque feed forward compensation function are enabled at the
same time, the 14th and 15th bytes are used for TFF field and the parameter bank designation cannot be changed.
In this case, the latest bank settings will be maintained.
• If the BANK_SEL is allocated to the option field function bit, the BANK_SEL of the 14th byte will be invalid.
Unless the 14th byte is used for interpolation torque feed forward compensation function, set it to 0.
• In the servo parameters, set the Bank Switching function for SGDV SERVOPACKs.
The Parameter Bank data (Pn902 to Pn95F) is not saved in the nonvolatile memory. So, always set these param-
eters when using MECHATROLINK networks.
