Product Description

The Kollmorgen S7720A-2CF2-PA is a digital servo amplifier that should be mounted in a closed control cabinet. The leakage current of the device is more than 3.5 mA. The first slot of the unit has the 2CAN expansion module, which provides the interfaces on different Sub-D connectors. Both CAN connectors are wired parallel. Unimpeded ventilation of the device should be ensured to avoid overheating. The setup software can be used to alter the settings of the product. However, any other alterations are likely to void the warranty. The equipment should be installed and wired only when it is not live.

The peak output current of the S700 digital servo amplifier for approximately five seconds is 140 Arms with a tolerance of +/- 3%. The bandwidth of the current controller of the unit is greater than 1.2 (bis 5) kHz. The depth of the device with connectors is 285 mm, and its depth without connectors is 244 mm. The product can be stored for less than one year without any limitations. The available documentation should be read thoroughly before the installation and commissioning of the device. Inappropriate handling of the unit can cause damage to property and harm to people.

The surface of the S700 digital servo amplifier can be very hot in operation. There is a high risk of minor burns. The surface temperature of the unit can exceed 80°C. So, before touching it, the temperature must be measured, and then wait until the temperature of the motor has dropped below 40°C. The servo amplifier should be safely earthed to the protective earth busbar in the switchgear cabinet. Without low-resistance earthing, personal protection cannot be guaranteed.
