(r52287), but is evaluated with p50115.
EMF at 100% speed
(1.00 to 140.00% of device rated supply voltage (p50078[0]))
Remark:
The value set here determines the 100% speed for the closed-loop speed
control.
Speed in rpm for EMF set on p50115[0]
Comment 1:
Parameter p2000 is used to convert from a "physical speed" (rpm) into a
"relative speed" (%) and vice versa.
This conversion is required for:
• Speed setpoint input via the control panel in STARTER
• Speed setpoint input via the operating screen form at the AOP30
• Calculation of display values r0020, r0021, r0060 and r0063
Remark 2:
Parameter p2000 and parameters r0020, r0021, r0060 and r0063 are not
data-set dependent. This is the reason why the physical speed can only be
displayed correctly for one data set (DDS).
Number of the parameter that is switched to the actual speed controller
value
Speed in rpm at which the parameter selected on p50609[0] accepts the
