Product Description

The S7720F-2CF2-S4 is a versatile digital servo amplifier from Kollmorgen. The device has three slots for expansion cards. The first slot is equipped with a 2CAN expansion module, which provides the interfaces on separate Sub-D connectors. The controlled fan is present in the second slot. It can be switched on and off, or depending on the temperature values, it runs at 50% rated speed, which reduces the average noise emission of the unit. The third slot contains a S1-2, SIL 2 safety card. The device contains electrostatically sensitive components, which are likely to be damaged by incorrect handling.

The bandwidth of the current controller of the S700 digital servo amplifier is greater than 1.2 (bis 5) kHz. The unit’s residual voltage drop at the rated current is 6 V. The maximum noise emission of the product is 68 dB(A). The height of the unit without the connectors and shielding plate is 386 mm. The depth of the device with connectors is 285 mm. The product is 190 mm wide. The switching frequency of the output stage of the device is 8 kHz. The ambient storage temperature of the servo amplifier is between -25°C and +55°C.

The servo amplifier must be safeguarded from impermissible stress. The user should not allow any components to bend or any insulation distances to change during handling and transport. Contact with electronic contacts and components should be avoided. The device will turn itself off when it gets overheated. Care should be taken to ensure that there is a sufficient flow of cool, filtered air into the control cabinet. There are warning signs on the housing of the device. The unit should not be altered without permission from the manufacturer.
