Overcurrent Protection
The standard SIKOSTART controller is not equipped with
overload protection.
The user must provide overload
protection.
Ratings for Frequent Starts and
Occasional

period:
Controller rating to be 200% of motor rating.
Very Severe
- 10 times in any

Initial Voltage
30% to 80% of nominal voltage (approximately 10% to 64% on
normal starting torque)
*Acceleration time of the motor will probably be less than the
Start Time setting and will vary depending on the load friction
and inertia characteristics of the system.
