Product Description:
The S7720C-NANA-S3 Kollmorgen digital servo amplifier has a S1-2, SIL 3 safety card in the third expansion slot. This servo amplifier has no other expansion cards. The product renders high speed, current, and position control that helps in achieving a high machine cycle rate. This device must not be mounted directly near equipment that generates magnetic fields. The unit has to be installed in a site free from conductive or corrosive materials. It has a rated input power of 50 kVA for continuous operation. This amplifier must be handled by ensuring that its insulation distances do not get altered.
The product must have unimpeded ventilation with the required space above and below it. This device must be assembled along with the choke on a conductive grounded mounting plate in the cabinet. The unit should be properly earthed before it is operated. Its screws for mounting onto the backplane of the control cabinet are fixed in place using a 4 mm Allen key. This amplifier must not have a flatness of more than 25 µm for the mounting plate.
The product can be combined with several other amplifiers using a common DC bus link circuit. This device must be installed and wired only when it is not in the live state. The unit must not be associated with extended feedback lines as this can cause the shielding to be interrupted. It must be ensured that the lines between servo amplifiers are always shielded. This servo amplifier has an EMC compliant shielding and grounding. The product has a capacitance of less than 150 pF/m for the motor cable.
Frequently Asked Questions about S7720C-NANA-S3:
Q: What is a major advantage of the STO function of the S700 amplifier?
A: The DC bus link of the S700 amplifier remains charged up because of the STO safety function.
Q: What is the input current rating of the STO inputs of the S700 amplifier?
A: The input current rating of the STO inputs of the S700 amplifier is 33 mA to 40 A.
Q: What is the leakage current over the protective earth conductor of the S700 amplifier?
A: The leakage current over the protective earth conductor of the S700 amplifier is more than 3.5 mA.
Q: What happens when the S700 amplifier is used with a painted mounting plate?
A: When the S700 amplifier is used with a painted mounting plate, its electrostatically sensitive components get discharged.
Q: How are the STO enable inputs of the STO amplifier switched?
A: The STO enable inputs of the STO amplifier are switched according to a defined test sequence.
