6.1.6
Fixed speed setpoint (from SW 3.1)
Speed setpoints can be defined in parameters using this function. The
required fixed setpoint for the speed setpoint input is selected via input
signals. The currently selected fixed setpoint can be displayed via out-
put signals.
Advantage:
An analog voltage is not required for the speed setpoint input, and the
setpoint can be precisely set.
The following signals are used for the ”fixed speed setpoint” function:
Input signals
(refer under index entry ”Input signal, digital – ...”)
– Fixed speed setpoint 1st input (function number = 15)
– Fixed speed setpoint 2nd input (function number = 16)
– Fixed speed setpoint 3rd input (function number = 17)
– Fixed speed setpoint 4th input (function number = 18)
Output signals
(refer under the index entry, ”Output signal, digital – ...”)
– Status, fixed speed setpoint 1st output (function number = 15)
– Status, fixed speed setpoint 2nd output (function number = 16)
– Status, fixed speed setpoint 3rd output (function number = 17)
– Status, fixed speed setpoint 4th output (function number = 18)
The following parameters are available for the ”fixed speed setpoint”
function:
P0641:16
Fixed speed setpoint (SRM, ARM)
Fixed velocity setpoint (SLM)
The following sequence is practical when commissioning:
1. Enter the required fixed speed setpoints (refer to Chapter A.1)
P0641:0 = no significance
P0641:1 = required fixed setpoint 1
P0641:2 = required fixed setpoint 2, etc.
2. Parameterize the input terminals (refer to Chapters 6.4.2 and 6.4.3)
3. Parameterize the output terminals (refer to Chapters 6.4.5 and 6.4.6)
4. Check the function
