27
Ramp-up procedure completed (V390x 4002.2)
This signal confirms that the actual speed value has reached the new setpoint allowing for
the tolerance band set in the drive. The ramp-up procedure is thus completed. Any
subsequent speed fluctuations due to load changes will not affect the interface signal.
|M
d
| < M
dx
(V390x 4002.3)
This signal indicates that the current torque |M
d
| is lower than the threshold torque M
dx
set in
the drive:
|n
act
| < n
min
(V390x 4002.4)
This signal indicates that the actual speed |n
act
| is lower than the set minimum speed n
min
.
n
act
| < n
x
(V390x 4002.5)
This signal indicates that the actual speed |n
act
| is lower than the set threshold speed n
x
.
n
act
= n
set
(V390x 4002.6)
The PLC receives this signal confirming that the actual speed n
act
has reached the new
setpoint allowing for the tolerance band set in the drive and continues to remain within the
tolerance band.

Signals from PLC to HMI
OP key disable (V1900 5000.2)
IS "OP key disable" can be applied to disable (1 signal) or enable (0 signal) the connected
keyboard.
Program number (VB1700 1000)
A declared program number is transferred from the PLC to HMI if a NC program is selected
by the PLC. The current NC program selected can be stored via the command interface (see
VB 1700 1001) and also selected again.
With SINUMERIK 802D sl, a program with the program name (STRING) is administered. To
assign a program name to a program number, the file PLCPROG.LST is available in the
control. In this assignment list, the names for a maximum of 255 programs can be declared
and assigned.
