⚠ Notice : The information for 17Lf series shown on the website is for advance publicity. We are happy to release 17Lf series in the third quarter of 2024 after completing certifications and technical documentations. The drawings have already been listed on the digital archive, and other technical data such as user manuals, datasheet will be posted in advance as soon as they are ready.

Overview – 17Lf Servo Series

The new mightyZAP servo series with a 17mm diameter motor which improve durability. Provide faster speed under the same rated load specification comparing to the 12Lf series.   Overall functionality is almost same as the 12Lf series, but only RS-485 communication and MODBUS RTU protocol are provided, and user expandability has been improved with the expansion I/O port.

17Lf Servo Series Features

  • Compact size with built-in drive, position sensor, DC motor and gear box
  • Better durability & faster speed under similar rated load comparing to 12Lf series thanks to the bigger 17mm diameter DC motor
  • Position, current and speed control along with position & current feedback
  • Easy digital I/O control through 4 x Expansion I/O ports (No coding)
  • 27/37/50/87mm(*) stroke option
    – (*): Each 3mm stroke can be added when adjusting the long stroke limit through Total Manager software.
  • Rated load of 17N~70N depending on the lead angle for each stroke
    – Speed is inversely proportional to the rated load, so the higher the rated load, the slower the speed.
  • RS-485 MODBUS-RTU protocol applied (IR open protocol is not provided)
  • Action feature which enables user’s motion save & run
