Description
Drive A
Drive B
663
X431.4
Pulse enable,
module–specific
The inverter is enabled (motor control), if the enable voltage is
available at the following terminals:
1. Terminal 63 (pulse enable, group–specific,
at the NE and monitoring module)
2. Terminal 64 (controller enable, group–specific,
at the NE or monitoring module)
3. Terminal 48 (contactor control, at the NE module)
4. Terminal 663 (pulse enable, board–specific)
5. Terminal 65.x (controller enable, axis–specific)
If terminal 663 is opened while the motor is rotating, the inverter is
immediately (< 1 ms) inhibited, and the motors connected to this
module coast down in a no–current condition.
If the module is enabled using terminal 663, then the enable oper-
ation takes approx. 20 ms.

X452.5
Axis–specific
controller
enable
The controller enable is dependent on the following enable sig-
nals:
1. Terminal 63 (pulse enable, group–specific,
at the NE and monitoring module)
2. Terminal 64 (controller enable, group–specific,
at the NE or monitoring module)
3. Terminal 663 (pulse enable, board–specific)
4. Terminal 65.x (controller enable, axis–specific)
5. RFG, fault drive x (internal enable signal)
6. PROFIBUS enable signals
If the associated terminal 65.x is opened while the motor is rotat-
ing, then the drive brakes along the ramp–function generator
ramp.
If the n
min
threshold (P1403) is exceeded (as absolute value), or
after the pulse cancellation timer has expired (P1404), the inverter
is inhibited (pulses canceled), and the motor is shutdown without
any overshoot.
Note:
x:
Space retainer for drive A or B
If the enable signals are missing, which are required to operate the drive, these can be determined
using P0600 (operating display) (refer to Chapter 4.5).
