Ramp Switching

This function allows switching between the first and second ramps. The

first ramps are ACC and dEC, the second ramps are AC2 and dE2. There

are two ways to activate the function:

• Assign a logic input to RP2 and close the assigned input (set it to

state 1).

• By detection of a frequency threshold. This must be configured with

the Frt parameter.

If a logic input is assigned to the function, ramp switching can only be

initiated by the assigned input.

Jog

A logic input can be assigned to the Jog function to define a motor speed

from 0 to 10 Hz. A run command (FWD or REV) is also required.

If the Jog contact is closed (set to state 1) and then a run command is

given, the acceleration ramp is 0.1 s. The deceleration ramp will be 0.1 s

when the run command is removed.

If a run command is given and then the Jog contact is closed (set to

state 1):

• The acceleration ramp (ACC) is 0.1 s if the motor speed is less than

the programmed Jog speed.

• The deceleration ramp (dEC) is followed if the motor speed is higher

than the programmed Jog speed.

When the Jog contact is opened (set to state 0), the ACC and dEC

settings are used to adjust the motor speed.

The following Jog parameters can be modified in the 2—Adjust menu:

• Jog speed (JOG)

• Delay between jog pulses (JGt)
