Main Voltage Required (± 15%) In Line Application: 200/460V AC or 400/600V AC
(specified by catalog no.)
Inside Delta Application: 200/400V AC or
400/600V AC (specified by catalog no.)
Control Voltage Required 24V DC, 120V AC, or 230V AC, +10%, -15%
(specified by catalog no.)
Control power requirements are listed below.
AC Frequency & Phase 50/60 Hz, working 45 to 65 Hz; 3 phase
Temperature Range 0v to 50vC (32v to 122vF), inside enclosure in which unit is
mounted. Derate 33% for each 10vC over 50vC to a max-
imum of 70vC.
Permissible Altitude 1000m at rated output
2000m at 0.87*le
3000m at 0.77*le
Overcurrent Protection The standard SIKOSTART controller is not equipped with
overload protection. The user must provide overload
protection.
Ratings for Frequent Starts and Occasional - 20 times in any 60 minute period:
Stops, Plugging or Jogging Applications Controller rating to be 133% of motor rating.
Severe - 5 times in any 60 second period:
Controller rating to be 200% of motor rating.
Very Severe - 10 times in any 60 second period:
Controller rating to be 300% of motor rating.

Adjustment Ranges -
16 settings each:
Start Time (Accel Ramp) .5 to 60 seconds*
Stop Time (Decel Ramp) .5 to 60 seconds
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.
