Option
Function
[37]
Emergency
mode
A signal applied puts the drive into emergency mode and the preset ref bits 0–2 define the operation
mode of emergency mode where all other commands are disregarded. See parameter group 24-0*
Emergency Mode and parameter group 24-2* Emergency Mode 2.
[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.
[44]
Restart drive
[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.
[55]
DigiPot in-
crease
Increase signal to the digital potentiometer function described in parameter group 3-9* Digital Pot. Me-
ter.
[56]
DigiPot De-
crease
Decrease signal to the digital potentiometer function described in parameter group 3-9* Digital Pot. Me-
ter.
[57]
DigiPot Clear
Clears the digital potentiometer reference described in parameter group 3-9* Digital Pot. Meter.
[58]
DigiPot hoist
[60]
Counter A (up)
(Terminal 29 or 33 only). Input for increment counting in the SLC counter.
[61]
Counter A
(down)
(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] Extended
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.
