MAGNETEK HPV1000 AC Elevator Drive Technical Manual 77
General Application Precautions
Motor Selection
Drive Capacity
The output current should not exceed 150% of the drive rated current. Select a drive that can output enough current when
accelerating a load at 100%.
For specialized motors, make sure that the motor rated current is less than the rated output current for the drive.
Starting Torque
The startup and acceleration characteristics of the motor are restricted to the drive's overload current rating (150% rated
current for 60 s).
The overload rating for the drive determines the starting and accelerating characteristics of the motor. Expect lower
torque than when running from line power. To get more starting torque, use a larger drive or increase both the motor and
drive capacity.
Stopping
Fast Stop
When the drive faults out, a protective circuit is activated and drive output is shut off. This, however, does not stop the
motor immediately. A mechanical brake may be required to stop the motor if Fast Stop deceleration is insufficient.
Mechanical Brake
A mechanical brake is required to prevent the elevator from free falling during a drive fault condition.
Repetitive Starting/Stopping
Elevators and other applications with frequent starts and stops often approach 150% of their rated current values. Heat
stress generated from repetitive high current will shorten the life span of the IGBTs. The expected lifetime for the IGBTs
is about 3 million start and stop cycles with a default carrier frequency of 2 kHz, 5 kHz (HPV1000-4112 to
HPV1000-4150), or 8 kHz (HPV1000-4009 to HPV1000-4091) and a 150% peak current.
Equipment Hazard
Do not modify the drive circuitry.
Failure to comply could result in damage to the drive and will void warranty.
Magnetek is not responsible for any modification of the product made by the user. This product must not be modified.
Failure to comply could result in damage to the drive or braking circuit.
Observe proper electrostatic discharge procedures (ESD) when handling the drive, circuit boards, and option
cards.
Failure to comply may result in ESD damage to the drive circuitry.
Do not operate damaged equipment.
Failure to comply could result in further damage to the equipment.
Do not connect or operate any equipment with visible damage or missing parts.
Do not lift the drive up while the cover is removed.
This can damage the terminal board and other components.
Do not expose the drive to halogen group disinfectants.
Failure to comply may cause damage to the electrical components in the drive.
Do not pack the drive in wooden materials that have been fumigated or sterilized.
Do not sterilize the entire package after the product is packed.
