11.3 SLEEP MODE
The Sleep mode allows the inverter to turn off the motor when the speed reference is below the value programmed
in P0217 for a period defined by P0218. In this way, the speed reference itself is able to turn off the motor, reducing
the energy consumption. Besides, there is no need of digital command to drive the motor, that is, the reference
also actuates as a logical command.
When the PID controller is active, the condition for the Sleep mode is incremented by P0535, besides parameters
P0217 and P0218. This condition adds a minimum deviation criterion of the process variable in relation to the
setpoint (error), ensuring that the PID keeps the process variable control over the Sleep mode. For further details,
refer to
Section 13.3 SLEEP MODE WITH PID on page 13-6 .
The Sleep mode is signaled in P0006 equal to 7.
