CHAPTER 8 – Operation with Profibus
SMT-BD1/t
In speed mode (as from firmware EPROM version 506.64):
PPO2 or PPO4 must be used:
PZD2 contains the motor speed value (0x7FFF corresponds to the maximum motor speed).
PZD5 contains the current monitor (0x7FFF corresponds to the maximum current).

Notes:
ENABLE Enabling.
C.n
Indicates bit n of the control word (
S.n
Indicates bit n of the status word (
This diagram describes the amplifier behaviour.
The enabling process includes 5 stages: "ENABLE inhibited", "ENABLE not ready", "Ready for ENABLE",
"Ready" and "Operation enabled".
