Product Description:
The Kollmorgen S7720A-SEF2-PA is a digital servo amplifier in the S700 series that comes with a memory card for firmware and parameter updates. Care should be taken to ensure that the device does not come into contact with plastic films or artificial fabrics. The unit must always be placed on a conductive surface. The product should not be sprayed with or immersed in water or any other liquid for cleaning or other purposes. Only 60°C or 75°C copper wires should be used for wiring the unit. The servo amplifier is not equipped with motor over-temperature sensing.
The ambient operating temperature of the S700 digital servo amplifier is +40 to +55°C with a power derating of 2.5%/K. The device has a pollution level of 2 according to IEC 60664-1 specifications. There is a built-in fan for ventilation. The product has a three-character LED display, which shows the amplifier status after turning on the 24 V supply. The functional safe restart lock STO secures the drive in standstill mode with its internal electronics. This prevents the drive shaft from an unintentional restart even when power is supplied.
The S700 digital servo amplifier must be protected from impermissible stress. During handling and transport, the user should ensure that components do not bend, or the insulation distances get altered. The device must not come into contact with electronic components and contacts. When it comes to connection conditions, the technical data and specifications mentioned in the rating plate and documentation must be strictly observed. The servo amplifier is prone to damage if the permissible voltage or current values are exceeded.
Frequently Asked Questions about S7720A-PBF2-PA:
Q: Can the S700 digital servo amplifier directly control a holding brake in the motor?
A: Yes, the S700 digital servo amplifier can directly control a 24V holding brake with up to 3 A in the motor.
Q: Can devices that produce magnetic fields be mounted close to the S700 digital servo amplifier?
A: No, devices that produce magnetic fields should not be mounted close to the S700 digital servo amplifier because strong magnetic fields can directly affect the internal parts of the device.
Q: Does the S700 digital servo amplifier have warning signs?
A: Yes, the S700 digital servo amplifier has warning signs added to its housing. If they are damaged, they should be replaced immediately.
Q: What is the recommended tightening torque of the grounding bold of the S700 digital servo amplifier?
A: The recommended tightening torque of the grounding bolt of the S700 digital servo amplifier is 3.5 Nm.
Q: What should be done if the motor cables of the S700 digital servo amplifier are longer than 25m?
A: If the motor cables of the S700 digital servo amplifier are longer than 25m, it may be necessary to use a motor choke (3YLN) depending on the system.
