Speed in RPMs (max 32767)
• RPM is calculated based on P305 and P304
• Example 1 (P305 = 1750 RPM, P304 = 60 Hz):
Requested speed command 25.0 Hz = 25.0 x 1750/60 = 729 = 0x02D9
NOTE
To use this Output assembly (20) Network Control and Network Reference must be set using explicit
communication by writing into the control word at NetId 65 – the bit configuration of this word matches the
WORD 0 of output assembly 100.

NOTE
In order to Start/Stop the drive via network control, bit 5 of Word 0 must be set in this assembly.
In order to control the speed via network communications, bit 6 of Word 0 must be set in this assembly.
