5.3.1 DRIVE READY
The Drive Ready condition (o.L.0=H) is given by alarms are not active and at the same time both the
software and hardware enables:
* The software enable, given by state of the connection C29, (C29=1 of default).
* The external enable (the function of the input is assigned to the default input L.I.2)
If an enable is missing or an alarm is active, the ready drive signal goes into an non-active state
o.L.0=L and this state remains until the causes that brought about the alarm conditions are removed
and the alarms are reset. An alarm reset can be achieved by activating the function “Alarm reset”
that, by default, is assigned to input L.1 (or setting C30=1).
Keep in mind that the “Alarm reset” is achieved by the active front of the signal, not on the active
level.
5.3.2 DRIVE SWITCH ON / RUN
When the drive is “Ready to switch on / RUN” o.L.0=H, motor may start running “Drive switch on/run”
o.L.3=H, by activating both the hardware and software switch on enables:
* Function “Logic switch on/RUN input” (default input 4 assigned) RUN=H
* Software switch on/RUN C21 (C21=1) is active by default.
Switch on/RUN disable and enable (from STOP offline, to RUN online) is given by the logic of the
following table:
Drive ready o.L.0 Switch on / RUN C21 ON-LINE
L X X L
H L X L
H X 0 L
H H 1 H
It is mentioned that the input function “Switch on/RUN input” can given also via serial line or field-bus.
See for details the Standard Application Manual.
