Definition of the control word

The control word is 16 bits wide. Each bit has been assigned a frequency inverter function. The low byte consists of 8 fixed function bits that are always valid. The assignment of the more significant control bits varies for the different control words.

Functions that are generally not supported by the frequency inverter cannot be activated by the control word. The individual control word bits are considered as reserved and must be set to logical 0 by the user.
