Product Description

The Kollmorgen S7720A-SNF2-PM is a digital servo amplifier that is designed to be operated as an integral component of an electrical machine. The device has the fastest feedback evaluation. The unit should always be mounted within a closed control cabinet. Cooling or ventilation is necessary to maintain the temperature within the cabinet under 40°C. The product should be transported only by qualified personnel in the original recyclable packaging supplied by the manufacturer. The servo amplifier must always be placed on a conductive surface. The unit should be packed in recyclable cardboard with inserts.

The repair of the S700 digital servo amplifier should be performed by the manufacturer. Opening the unit voids the warranty. The device is likely to cause high-frequency interference in non-industrial environments. Additional external EMC filters for interference suppression may be required in such cases. The unit has an integrated 24V step/direction interface meant for connecting the motor to the stepper controller. The Stop function of the product is used to shut down the machine when it is in normal operation.

The peak output current of the S700 digital servo amplifier for approximately 5 seconds is 140 Arms with a tolerance of +/- 3%. The rated DC bus link voltage of the unit is 290 to 675 V. The maximum permissible temperature at which the device can be transported is 70°C. Devices that produce magnetic fields should never be directly mounted beside the servo amplifier. This is because strong magnetic fields can affect the internal components of the drive. Such devices must be placed a little away from the servo amplifier, or the magnetic fields should be shielded.
