Soft Start Parameters
The ASTAT-XT incorporates five starting curves to enable you to select a suitable torque curve.
Soft Start Curve 0
– Standard curve (Default). This curve is the most suitable curve for preventing prolonged
starting and motor overheating.
Note:
When ASTAT-XT is connected in
DELTA Conf
., the ASTAT-XT will always use
Curve 0
regardless of the curve
defined.
