10.4.2 Controller inhibit
Description
If the controller inhibit is active, the power outputs are inhibited.
ƒ The drive idles to standstill without torque.
ƒ Keypad status display: Pulse inhibit
c
ƒ Status display of the controller: The green LED is blinking.
}
Danger!
Do not use controller inhibit (DCTRL1−CINH) as emergency off. The controller
inhibit only inhibits the power outputs and does not disconnect the controller
from the mains!
The drive could restart any time.

inhibit (CINH) −0− Controller inhibited (CINH) Controller can only be enabled if
X3/28 = HIGH ^ 277
−1− Controller enabled (CINH)
Activation
ƒ Via terminal X3/28:
– LOW level at the terminal activates the controller inhibit (cannot be inverted)
– HIGH level enables the controller again
ƒ Via digital signal (linking C0410/10 with a signal source):
– LOW level at the signal source activates the controller inhibit (level inversion is
possible with C0411)
– HIGH level releases the controller again
ƒ Via keypad (condition: C0469 = 1):
–
s activates the controller inhibit
–
u enables the controller again
ƒ Via code C0040:
– C0040 = 0 activates the controller inhibit
– C0040 = 1 enables the controller again
)
Note!
ƒ The sources for controller inhibit are ANDed, i. e. the drive only restarts
when the controller inhibit is cancelled at all signal sources.
ƒ The restart begins with an output frequency of 0 Hz, i.e. if the flying−restart
circuit is not activated, still rotating masses can lead to generative overload.
