HTL encoder function (only DIN2/4 )
For the evaluation of an HTL encoder, the digital inputs DIN2 and DIN4 must be parameterised with
the following functions.

encoder
This function
can only be
used for digital
inputs 2 (DIN2)
and 4 (DIN4)
!
A 24V HTL encoder can be connected to DIN 2 and DIN 4 in order to
measure the speed. The maximum frequency at the DIN is limited to
10kHz. Accordingly, a suitable encoder (low pulse number) or
suitable mounting (slow speed) SHOULD BE USED.
The direction of counting can be changed by exchanging the
functions on the digital inputs.
Further settings are in P461, P462, P463.

Setting of the stop time for the fast stop function which can be triggered either via a digital input,
the bus control, the keyboard or automatically in case of a fault.
Emergency stop time is the time for the linear frequency decrease from the set maximum
frequency (P105) to 0Hz. If an actual setpoint <100% is being used, the emergency stop time is
reduced correspondingly.

In the standard setting (P428 =0

Off
) the inverter requires a flank to enable (signal change
from "low high") at the relevant digital input.
In the setting On

1
the FI reacts to a High level. This function is only possible if the FI is
controlled using the digital inputs. (see P509=0/1)
In certain cases, the FI must start up directly when the mains are switched on. For this P428 = 1

On can be set. If the enable
signal is permanently switched on, or equipped with a cable
jumper, the FI starts up immediately.
NOTE: (P428) not "ON" if (P506) = 6, Danger! (See note on (P506))
