This function provides control of an external by-pass contactor,
significantly lowering heating losses and eliminating harmonics.
When the By-Pass function z is enabled, the programmable relay
output 2r is automatically assigned to this function, and must be used
to control the external by-pass contactor
Enables or disables the DC brake function
When the DC Brake function B is enabled, the programmable relay
output 3r is automatically assigned to this function.
PON, PI3 or PI4 settings enable the DC Brake function just before
starting the motor. This is usefull to stop a fan which is rotating in
reverse at the starting time

Sets time between consecutive starts. Setting "0" disables
this function.
Loads the parameters from the E2PROM to the temporal
buffer
Loads default factory settings to the temporal buffer.
Allows up to four tries of automatic restart after a fault.
Setting 0 disables this function
.
Time between retries.
The unit trips if the line voltage decreases below the
percentage set. Setting 0 disables this protection.
Note:
Calibrate parameter U before enabling this
protection.
Delay trip time
The unit trips if the line voltage increases above the per-
centage set. Setting 0 disables this protection.
Note:
Calibrate parameter U before enabling this
protection.
Delay trip time
The unit trips if the current decreases below the percent-
age set. Setting 0 disables this protection.
Note:
Calibrate parameter U before enabling this
protection.
Delay trip time
The unit trips if the current increases above the percent-
age set. Setting 0 disables this protection.

These are a secondary set of ramp up, ramp down and
starting torque parameters, which take over the primary
"a", "d" and "T" when the programmable function A is
enabled.
