How to configure limit hit situations
Example 1
: SMS trip limit hit
This example covers trip limit situations of SMS function with synchronous machines.
This example is valid when SMS-specific mute time is disabled (parameter
) or if encoder is used.
• parameter
= Disabled
• parameter
= 100 ms.
Note:
When a synchronous machine is started, there is a possibility of short (< 100
ms) error spikes in safe speed estimate which can cause an unnecessary trip if the
mute time is set too short. If the motor is rotated only in positive direction and
