DIGIFAS 7204

Product Description:

DIGIFAS 7204 is a Digifas 7200 series servo amplifier. It is designed and manufactured by Kollmorgen. The amplifier should only be used on a 3-phase industrial supply that operates at 400 Volts AC and is earthed. The amplifier is compatible with Kollmorgen 6SM series servo motors. It should be mounted inside a closed switch cabinet. A nameplate is attached to the unit. It lists relevant and important information that operators should verify at delivery. DIGIFAS 7204 is a standard amplifier that features four current types, analog setpoint input for speed, holding brake, and incremental position output. Configuration and operation of the amplifier can be performed from a PC with the BS7200 software. Digital functions supported by the unit include speed and current control and resolver evaluation.

Input voltage rating of the DIGIFAS 7204 amplifier is 80 to 400 Volts (three-phase, 50/60 Hz). The unit can support output S1 load of 2.5 kVA. Rating for the intermediate circuit voltage is 560 Volts. The rated output current is 4.2 Amps and the peak output current is 8.4 Amps for 5 seconds. Switch on threshold for the ballast circuit is 720 Volts and the switch off threshold is 680 Volts. The pulse power of the ballast circuit is 2.3 kW for 1 second. The amplifier supports minimum 8 millihenry motor inductance. Clock frequency of the output stage is 8.33 kilohertz. Power loss at rated output current is 60 Watts. Weight of the servo amplifier is 2.1 kilograms and its dimensions are 275 x 71 x 235 millimeters. During operation, the ambient temperature should be between 0 and 45 degrees Celsius. Protection class of the amplifier unit is IP20.
