Option Function
[40] Latched precise
A latched precise start only requires a pulse of 3 ms on terminals 18 or 19. When using for parameter
start
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
Sends a latched stop signal when the precise stop function is activated in parameter 1-83 Precise Stop
stop inverse
Function. The latched precise stop inverse function is available for terminals 18 or 19.
[51] External inter- This function makes it possible to give an external fault to the drive. This fault is treated in the same
lock way as an internally generated alarm.
[55] DigiPot increase
Increase signal to the digital potentiometer function described in parameter group 3-9* Digital Pot. Me-
ter.
[56] DigiPot De-
Decrease signal to the digital potentiometer function described in parameter group 3-9* Digital Pot.
crease
Meter.
[57] DigiPot Clear
Clears the digital potentiometer reference described in parameter group 3-9* Digital Pot. Meter.
[60] Counter A (up) (Terminal 29 or 33 only). Input for increment counting in the SLC counter.
[61] Counter A (Terminal 29 or 33 only). Input for decrement counting in the SLC counter.
(down)
[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 (Terminal 29 or 33 only). Input for decrement counting in the SLC counter.
(down)
[65] Reset Counter B Input for reset of counter B.
[70] Mech. Brake
Brake feedback for hoisting applications: Set parameter 1-01 Motor Control Principle to [3] Flux w/ motor
Feedback
feedback; set parameter 1-72 Start Function to [6] Hoist mech brake Ref.
[71] Mech. Brake Inverted brake feedback for hoisting applications.

[72] PID error in- When enabled, this option inverts the resulting error from the process PID controller. Available only if
verse 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 The functionality is the same as the corresponding control word bit of the PROFIBUS/PROFINET op-
OFF2 tion.
[92] PROFIdrive The functionality is the same as the corresponding control word bit of the PROFIBUS/PROFINET op-
OFF3 tion.
[94] Light Load De- Light-load detection is a feature for lift application to ensure that the lift runs in the evacuation direc-
tection tion which requires the least energy (UPS capacity), during an emergency. See parameter 30-25 Light
