Categorization by frame size and option code
The frame size identifies information which concerns only a certain frame size of the drive.
The frame size is shown on the type designation label. All frame sizes are listed in the
technical data.
The option code (for example, option +E200) identifies information which concerns only a
certain optional selection. The options included in the drive are listed on the type designation
label.
Use of component designations
Some device names in the manual include the item designation in brackets, for example
[Q20], to make it possible to identify the components in the circuit diagrams of the drive.
