Product Description

The Kollmorgen S7720A-NANA-F2 digital servo amplifier must be wired according to its connection diagram. This servo amplifier can be operated with other amplifiers of the same series off a common DC bus link with a built-in brake circuit without implementing any additional measures. The product has an expansion card only in its third slot. This device is CE Certified. The unit must comply with the specifications given for its connection conditions. It is likely to get damaged when it is used with an unsuitable motor. This amplifier must not be modified by the user.

The product should be free of condensation all the time. This device can be disposed in accordance with the WEEE-2012/19/EU guidelines. The unit has a rated DC link voltage of 290 VDC to 675 VDC. Its electrical installation must be done by qualified and trained personnel using the prescribed personnel safety equipment. This amplifier is manufactured in compliance with RoHS Directive 2011/65/EU directives. The product related mating SubD connectors and braking resistors are supposed to be ordered separately.

This device can be used on a TN-network or TT-network with a grounded neutral point and 42 kA maximum symmetrical current rating. The unit has various programmable logical combinations of digital signals. Its voltage rise speed at 3 x 230 VAC is 2.3 kV/µs. This servo amplifier shuts down by itself whenever F01 and F13 fault codes are encountered. The product must have the VBUSBAL value set to 4 when a 480 V mains supply is used. This device behaves according to how its parameters have been set. The unit triggers a controlled emergency braking followed by a disabling of the output stage when the ACTFAULT parameter is set to 1.
