Description
Defines the slip gain for the motor slip compensation control. 100% means
full slip compensation, 0% means no slip compensation. Other values can be
used if a static speed error is detected despite of the full slip compensation.
Example: 35 Hz constant speed reference is given to the drive. Despite of the
full slip compensation (SLIP COMP RATIO = 100%), a manual tachometer
measurement from the motor axis gives a speed value of 34 Hz. The static
speed error is 35 Hz - 34 Hz = 1 Hz. To compensate the error, the slip gain
should be increased.
Slip gain
Programmable protection functions
Selects how the drive reacts when an analog input signal falls below the set
minimum limit.
Protection is inactive.
The drive trips on fault AI1 LOSS (code: F0007) and the motor coasts to stop.
Fault limit is defined by parameter
The drive generates alarm AI1 LOSS (code: A2006) and sets the speed to
the value defined by parameter
defined by parameter 3021
WARNING! Make sure that it is safe to continue operation in case
the analog input signal is lost.
The drive generates alarm AI1 LOSS (code: A2006) and freezes the speed to
the level the drive was operating at. The speed is determined by the average
speed over the previous 10 seconds. The alarm limit is defined by parameter
3021 AI1 FAULT LIMIT.
WARNING! Make sure that it is safe to continue operation in case
the analog input signal is lost.
Selects an interface for an external fault 1 signal.
Not selected
External fault indication through digital input DI1. 1: Fault trip (EXT FAULT 1,
code: F0014). Motor coasts to stop. 0: No external fault.
