Increase E.P. and Decrease E.P.
(Electronic Potentiometer): They are active when +24 V is applied (for
Increase E.P.) or 0 V (for Decrease E.P.) to the respective input configured for this function. It is also necessary
to set P0221 and/or P0222 in 7.
Multispeed:
The setting of parameters P0266 and/or P0267 and/or P0268 to 13 requires parameters P0221
and/or P0222 to be set to 8. Refer to section 7.3.11 for the description of parameters P0124 to P0131.
Speed/Torque:
This function selects the “Speed+Torque” control mode (P0299 = 0) with the application of 0 V
to the input, and the “Torque” control mode (P0299 = 1) with the application of 24 V.
Without External Alarm:
This function will display “External Alarm” (A090) on the keypad when the programmed
digital input is open (0 V). If +24 V is applied to the input, the alarm message will be automatically removed from
the keypad display. The converter continues operating normally, regardless the status of this input.
Without External Fault:
This function will make the converter disable the armature firing pulses and display
“External Fault” (F091) on the keypad when the programmed digital input is open (0 V). In order to be able to
enable the converter again, it is necessary to close the corresponding digital input (24 V) and reset it.
Speed Regulator Gains:
When this function is programmed and the input DIx is in +24 V, the speed regulator
will use the values of Proportional and Integral gains set in parameters P0161 and P0162. Otherwise, the gains
set in parameters P0159 and P0160 will be used.
Parameterization Off:
When this function is programmed and the DIx input is +24 V, parameters cannot be
changed, no matter the values set in P0000 to P0200. When the DIx input is 0V, the modification of parameters
will depend on the values set in P0000 and P0200
Load User 1/2:
This function allows selecting the user’s memory 1 or 2 from a transition in DIx programmed for
this option.
When the status of the DIx changes from low level to high level (transition from 0V to 24V), the user’s memory 1
will be loaded, since the content of the present parameters of the converter has been previously transferred to
the parameter memory 1 (P0204 = 7).
When the status of the DIx changes from high level to low level (transition from 24 V to 0 V), the user’s memory
2 will be loaded, since the content of the present parameters of the converter has been previously transferred to
the parameter memory 2 (P0204 = 8).

Load User 3:
This function allows selecting the user’s memory 3 from a transition in DIx programmed for this
option.
When the status of the Dix changes from low level to high level (transition from 0 V to 24 V), the user’s memory
3 will be loaded, since the content of the present parameters of the converter has been previously transferred to
the parameter memory 3 (P0204 = 9).
