CU834-002

Product Description:

The CU834-002 servo drive sits inside the PC800 - PCE800 Brushless Servo Drives series designed by Pacific Scientific, built mostly for industrial automation needing solid performance and just enough flexibility. This drive handles a continuous output current of 7.1 A RMS at temperatures between 25 and 40°C, giving a enough-for-most constant current for demanding loads with changes through the workday. Keeping up with modern setups, it accepts 180–265 VAC (3-phase) as input, a range that fits plenty of factory power systems and keeps wiring simple. Efficiency is sharp too—marked by its 98% power stage efficiency—so most of that incoming energy moves right through to the motor instead of warming the control cabinet.

Peak loads get coverage by the 21.2 A RMS peak output current, which is handy when things surge or a motion step asks for more strength than usual. Commands come in over multiple routes: the interface options here range from RS-232/485 for digital control, plus analog ±V DC, indexing, and step/dir. Choices like that make plugging into assorted newer or older controls easy. Sometimes the wiring can't be short; this model deals with motor power cables up to 50 meters, which gives plenty of room to stretch along production lines or across a wide machine base. Even in high-cutoff shopper environments—say, up to 1,500 meters altitude—the drive keeps things running, no trouble.

Some factory settings hit sudden heat, chill, or splash, so safety features matter. The storage range spreads out from -40°C up to +70°C, and operation brings a tight control on damaging ripple or spikes using 16 kHz output current ripple frequency. Coating and design push resistance against 10% to 90% humidity (non-condensing), handy where climates shift with the season or sweat shows up on chilly pipes.
