{ 10.0 }
0.1 ... 250.0 = The time interval between the expected Watchdog signals (programmable function
of the digital inputs P420 – P425). If this time interval elapses without a pulse being
registered, switch off and error message E012 are actuated.
0.0 = customer error: As soon as a high-low flank or a low signal is detected at a digital input
(function 18) the FI switches off with error message E012.
-250.0 … -0.1 = Rotor running watchdog: In this setting the rotor running watchdog is active.
The time is defined by the number of the value which has been set. When the FI is
switched off, there is no watchdog message. After each enable, a pulse must first
be received before the watchdog is activated.

The actual speed list value supplied to the FI by an HTL incremental encoder can be used for
various functions in the FI. (The settings are identical to (P325)). The HTL encoder is connected
via digital inputs 2 and 4. The parameters (P421) and (P423) must be set accordingly to functions
43 "Track A" and 44 "Track B". Due to the frequency limit (max. 10 kHz) only restricted encoder
solutions (P462) are possible with these digital inputs. The mounting location (motor shaft or
output side) of the encoders is taken into account by the parameterisation of an appropriate speed
ratio (P463).
0 = Speed measurement Servo mode: The actual motor speed list value is used for the
servo mode. The ISD control cannot be switched off in this function.
1 = PID actual frequency value: The actual speed of a system is used for speed control.
This function can also be used for controlling a motor with a linear characteristic curve.
Here P413 and P414 determine the P and I proportion of the control.
2 = Frequency addition: The determined speed is added to the actual setpoint value.
3 = Frequency subtraction: The determined speed is subtracted from the actual setpoint.
4 = Maximum frequency: The maximum possible output frequency / speed is limited by the
speed of the encoder.
5 = Reserved: see BU510

Input of the pulse-count per rotation (16 - 8192) of the connected HTL incremental encoder.
If the direction of rotation of the encoder is not the same as that of the motor controller,
(depending on installation and wiring), it can be compensated for by selecting the corresponding
negative pulse numbers.
