Ramp Source
Parameter that allows you to select the source of the ramp and then the origin of the speed reference. Using the keys you can select the
source from among these:
•
NOT USED
: the speed reference is always fixed at zero.
•
ANALOG INPUT 1
: the speed reference is taken from the analog input 1. The parameter “Value” relative to this analog in-
put becomes the source of the ramp block.
•
DIGITAL REFER
: the speed reference is a digital value that can be set manually for testing or calibrating the motor. This
reference can also be digitally provided by a communication network (CAN BUS or other). To manually change this value,
see paragraph ”Digital Refer.“ just below.
•
ASW1 Output
: The speed reference is taken from the exit of the Analog Switch 1 block (see section 5.6.11 on page 68).
•
ASW2 Output
: The speed reference is taken from the exit of the Analog Switch 2block (see section 5.6.11 on page 68).
•
ASW3 Output
: The speed reference is taken from the exit of the Analog Switch 3block (see section 5.6.11 on page 68).
•
ASW4 Output
: The speed reference is taken from the exit of the Analog Switch 4block (see section 5.6.11 on page 68).
•
SumBlock Summ1
: The speed reference is taken from the “Summ1” output of the summing block (see paragraph 5.6.10 on
page 67).
•
SumBlock Summ2
: The speed reference is taken from the “Summ2” output of the summing block (see paragraph 5.6.10 on
page 67).
•
SumBlock Summ3
: The speed reference is taken from the “Summ3” output of the summing block (see paragraph 5.6.10 on
page 67).
Speed Ramp Time
Minimum Maximum
Units of measure
0.1
650.0
Sec
Parameter to set the up/down time of the speed ramp. Assuming an input of 0 to 100 % of the value is given, this parameter is defined
as the time the output (“Speed Demand”) takes to go from 0 % to 100 %.
Therefore if the input step goes from 0 % to 50 % it will mean that the time taken to finish the ramp will be half the time set on this
parameter.

%
With this parameter you can give a digital speed reference to the drive. This value can be changed manually via the keyboard or modi -
fied via a communication network (CAN BUS or other).
Aux Function
Menu group with parameters to adjust the auxiliary functions implemented within the drive.
Speed Threshold
Menu group with parameters to adjust the speed thresholds that generate a signal for the outside.
Threshold No. 1
Minimum Maximum
Units of measure
0
9999
RPM
Set the speed of the motor beyond which the associated digital output is switched.
Speed reached
Minimum Maximum
Units of measure
0.0
+10.0
%
Set the percentage difference between the set speed and the actual motor speed, to switch the digital output associated with the “Speed
reached” function.
Ext Torque Limit
Menu group with parameters to adjust the external torque limit function (see section ”External torque limit“ on page 63).
Torq. Lim. Source
This menu is used to select the source reference and enable the maximum torque limitation function provided by the motor. The pos-
sible selections are as follows:
•
NOT USED
: the torque limiter is not used, so it remains fixed at 100 % (visible on the parameter “Limit Output”).
