Product Description

The S7720F-PNF2-PM is a digital servo amplifier manufactured by Kollmorgen. The device has a rated current of 72 A and a rated voltage of 208 to 480 V. The electrical/mechanical option of the unit is coated PCBs. The amplifier has three slots. The second slot has a fan controller, and the third slot has the Posl/O expansion card. The device comes with a naming plate attached to its side for identification. The naming plate lists the technical details of the servo amplifier. The device features complete digital control. There is a three-character LED display to indicate the unit’s status.

The weight of the S700 digital servo amplifier is 13 kg. There is an in-built fan for ventilation. The height of the device, including the shielding plate and connectors, is 505 mm. The unit is 190 mm wide. The maximum noise emission of the servo amplifier is 68 dB (A). The thermal dissipation of the unit at a rated current of 3x400V without brake dissipation is 1005 W. The residual drop of the device at the rated current is 6 V. The amplifier has a permitted switch on/off frequency of 30 1/h. The product should always be mounted in a closed control cabinet.

The S700 digital servo amplifier and the power supply should be installed close together, on the grounded, conductive mounting plate in the control cabinet. The setup software of the unit can be used to change its settings. However, any other alternations are likely to invalidate the warranty. It should be noted that the equipment should be installed and wired up only when it is not live. The operator should ensure that neither the 24 V auxiliary voltage nor the electrical supply nor the supply voltages of any other connected equipment are turned on.
