Configuring Drive Parameters

The software lock function keeps personnel from accidentally changing parameters in the inverter memory. Use B031 to select from various protection levels.

The table below lists all combinations of B031 option codes and the ON/OFF state of the [SFT] input. Each Check ✔ or Ex ✘ indicates whether the corresponding parameter(s) can be edited. The Standard Parameters column below lists Low and High level access for some lock modes. These refer to the parameter tables throughout this chapter, each of which includes a column titled Run Mode Edit as shown to the right. The two marks (Check ✔ or Ex ✘) under the “Lo Hi” subtitle indicate whether Low-level and/or High-level access

applies to each parameter as defined in the table below. In some lock modes, you can edit only F001 and the Multi-speed parameter group that includes A020, A220, A320, A021–A035, and A038 (Jog). However, it does not include A019, Multi-speed operation selection. The editing access to B031 itself is unique, and is specified in the right-most two columns below.

NOTE: Since the software lock function B031 is always accessible when the motor is stopped, this feature is not the same as password protection used in other industrial control devices.
