Example 2: Rampref1 = + 400 rpm Rampref2 = - 600 rpm
Rampref= 400 rpm – 600 rpm = - 200 rpm
In Local mode the overall ramp reference is the result of the sum of the values with the Rampref3 and Rampref2
sign.
Example 1: Rampref3 = + 500 rpm Rampref2 = + 300 rpm
Rampref = 500 rpm + 300 rpm = 800 rpm
Example 2: Rampref3 = + 400 rpm Rampref2 = - 600 rpm
Rampref = 400 rpm – 600 rpm = - 200 rpm

5.3 604 Digrampref3 rpm INT16 16/32 0 CALCI CALCI ERW FVS
Setting of the digital ramp reference. The speed that the drive must reach after completing the acceleration phase
is set with the ramp reference. Variations in the ramp reference are made with the selected ramp times. The size of
the ramp reference determines the motor speed value. The sign determines the direction of rotation. The Rampref
parameter also refers to a minimum speed, if set. When the “Motorpotentiometer” or “Multispeed” functions are
selected the relative references are used. This reference can only be used in the Local mode.
The overall ramp reference is the result of the sum of the values with the Rampref3 and Rampref2 sign.
Example 1: Rampref3 = + 500 rpm Rampref2 = + 300 rpm
Rampref = 500 rpm + 300 rpm = 800 rpm
Example 2: Rampref3 = + 400 rpm Rampref2 = - 600 rpm
Rampref = 400 rpm – 600 rpm = - 200 rpm

Selection of the origin (source) of the reference signals on the input of the ramp function block, that denes the main
drive speed. The ramp reference values can be selected from among those listed in the “L_MLTREF” selection list.
When assigning the reference via terminals, signals with ±10V, 0 ...10V, 0... 20 mA and 4 ... 20 mA can be used.

Selection of the origin (source) of the signal that inverts the ramp reference output from the “Ramp ref” block. The signal
that can be used for this function can be selected from among those listed in the “L_DIGSEL2” selection list.

5.11 634 Rampreftoplim rpm INT32 0 0 CALCI ERWZ FVS
It denes the maximum value of the output of the ramp reference block, regardless of the signal that is present. The
ramp reference follows the reference signal from the value set in parameter PAR 636 Ramprefbottomlim up to
the value set with this parameter, after which the motor speed remains constant. The limit is valid for both directions
of rotation.
