The first slot contains the I/O extension card, the second slot has the fan controller, and the third slot is equipped with the Safety card S1-2, SIL 3. The electrical/mechanical option of the device is coated PCBs. The unit can be mounted in a vertical position. Only copper conductors must be used for wiring the servo amplifier. The device should be installed, operated, transported, and maintained only by properly qualified personnel. The unit features the fastest feedback evaluation in the market.

The S700 digital servo amplifier has a rated input power of 50 kVA for continuous operation. The rated output current of the device is 72 Arms at 3x208 V with a tolerance of +/- 3%. The peak output current of the servo amplifier is 140 Arms for approximately five seconds. The form factor of the output current of the device is 1.01. The height of the unit with connectors and shielding plate is 505 mm. Warning signs are added to the housing of the product. They should be replaced as soon as they are damaged. Before handling the components of the unit, the voltage in the DC bus link should be measured and only when the voltage drops below 60 V, the components be handled.

The exposed contacts of the S700 digital servo amplifier should not be touched because it can lead to a risk of severe injury or death. All covers and the cabinet door should remain closed during operation. The user should ensure that the device is earthed safely to the PE busbar in the switch cabinet. No personal protection can be ensured without low-resistance earthing.
