Product Description:

Sanyo Denki makes the PZ1A050A142S01 servo amplifier for tools that need high precision, speed control, and dynamic response. It is used in a lot of different types of machines, like lathes, grinding machines, and transfer machines.

The PZ1A050A142S01 servo amplifier works because of its 200V input. The servo amplifier is 235 mm tall and 225 mm deep overall. The connection part is 50 mm wide, and the servo amplifier is 75 mm wide. The fan is 65 mm wide. On the left side, the fixing holes are 80 mm from the centerline. On the right side, they are 85 mm from the centerline. There must be 5 mm of space at the top, 6 mm of space under the plugs at the bottom, and 5 mm of space on each side. A screw-type terminal block with the label TB handles control data and can handle I/O and feedback. A chart with alarm codes makes it easy to record errors by using blinking lights to show things like Over Current, Over Load, Amplifier Over Heat, Over Voltage, Over Speed, Position Error, Driver Error, Motor Position Error, and Fuse Protection. More fault tracking is possible with codes like SE, OVF, EXOH, and DSPE.

The organized layout of both the power connections and the control signals makes installation easy and fast. Connector connections and control ports that are clearly marked as FN, R, and FAN can be reached through the front panel. The PZ1A050A142S01 servo amplifier has a fan built in that guides airflow in the right direction. The R1, T1, T2, T3, U, V, and W labels on the terminal blocks show the three-phase power input and output lines for the motor. The servo amplifier is made to work continuously and supports apps that use precision machinery with stable performance.

Frequently Asked Questions about PZ1A050A142S01:

Q: How do clearances on PZ1A050A142S01 improve airflow efficiency?

A: The 5 mm top and side clearances and 6 mm bottom clearance allow proper ventilation. They prevent obstruction and support optimal fan airflow distribution.

Q: Why does PZ1A050A142S01 use terminal blocks labeled R1 and T1?

A: These terminal blocks provide correct power input alignment. They define input phases and outputs to U, V, and W that control motor connections and stability.

Q: How does the PZ1A050A142S01 alarm chart assist in fault reporting?

A: The alarm chart shows blink codes like OC, OV, and PE. It simplifies error identification and ensures operators quickly locate and resolve specific faults.

Q: Do labeled TB control terminals on PZ1A050A142S01 support integration?

A: Yes, TB screw terminals allow precise I/O and encoder feedback connections. This improves integration with external controls and guarantees stable signal transfer for precision machines.

Q: Why do wires on PZ1A050A142S01 have number tags?

A: The wires are tagged with numbers like 205 and 206. This prevents connection mistakes, improves maintenance work, and ensures accurate identification of all circuits.
