Function
[40]
Latched precise
start
A latched precise start only requires a pulse of 3 ms on terminals 18 or 19. When using for
parameter
1-83 Precise Stop Function[1] Cnt stop with reset
or
[2] Cnt stop w/o reset
: When the reference is reached,
the drive internally enables the precise stop signal. This means that the drive does the precise stop
when the counter value of
parameter 1-84 Precise Stop Counter Value
is reached.
[41]
Latched precise
stop inverse
Sends a latched stop signal when the precise stop function is activated in
parameter 1-83 Precise Stop
Function
. The latched precise stop inverse function is available for terminals 18 or 19.
[51]
External inter-
lock
This function makes it possible to give an external fault to the drive. This fault is treated in the same
way as an internally generated alarm.

(Terminal 29 or 33 only). Input for decrement counting in the SLC counter.
[62]
Reset Counter A
Input for reset of counter A.
[63]
Counter B (up)
(Terminal 29 or 33 only). Input for increment counting in the SLC counter.
[64]
Counter B
(down)
(Terminal 29 or 33 only). Input for decrement counting in the SLC counter.
[65]
Reset Counter B
Input for reset of counter B.
[70]
Mech. Brake
Feedback
Brake feedback for hoisting applications: Set
parameter 1-01 Motor Control Principle
to
[3] Flux w/ motor
feedback
; set
parameter 1-72 Start Function
to
[6] Hoist mech brake Ref
.
[71]
Mech. Brake
Feedback inv.
Inverted brake feedback for hoisting applications.
[72]
PID error in-
verse
When enabled, this option inverts the resulting error from the process PID controller. Available only if
parameter 1-00 Configuration Mode
is set to
[6] Surface Winder
,
[7] Extended PID Speed OL
, or
[8] Exten-
ded PID Speed CL
.
[73]
PID reset I-part
When enabled, this option resets the I-part of the process PID controller. Equivalent to
parameter 7-40
Process PID I-part Reset
. Available only if
parameter 1-00 Configuration Mode
is set to
[6] Surface Winder
,
[7] Extended PID Speed OL
, or
[8] Extended PID Speed CL
.
[74]
PID enable
Enables the extended process PID controller. Equivalent to
parameter 7-50 Process PID Extended PID
.
Available only if
parameter 1-00 Configuration Mode
is set to
[7] Extended PID Speed OL
or
[8] Extended
PID Speed CL
.
[80]
PTC Card 1
All digital inputs can be set to
[80] PTC Card 1
. However, only 1 digital input must be set to this option.
[91]
PROFIdrive
OFF2
The functionality is the same as the corresponding control word bit of the PROFIBUS/PROFINET op-
tion.
[92]
PROFIdrive
OFF3
The functionality is the same as the corresponding control word bit of the PROFIBUS/PROFINET op-
tion.
[94]
Light Load De-
tection
Light-load detection is a feature for lift application to ensure that the lift runs in the evacuation direc-
tion which requires the least energy (UPS capacity), during an emergency. See
parameter 30-25 Light
