  • Page 1 AC SPINDLE MDS-B-SPJ2 Series SPECIFICATION MANUAL BNP-B2164A(ENG)
  • Page 2 Make sure that this manual is delivered to the end user. Always store this manual for future reference. All specifications of the MDS-B-SPJ2 Series are listed in this manual. However, each CNC does not always apply to the specifications, so confirm the CNC specifications before using the unit.
  • Page 3 For Safe Use 1. Electric shock prevention DANGER Always turn the power OFF and wait 10 minutes or more until the charge lamp has turned OFF before wiring or carrying out inspections. Using a tester, etc., always confirm that there is no voltage between the P-N terminals before starting wiring or inspections.
  • Page 4 4. Various precautions Observe the following precautions. Incorrect handling of the unit could lead to faults, injuries and electric shocks, etc. (1) Transportation and installation CAUTION Correctly transport the product according to its weight. Do not stack the spindle motor or spindle amplifiers above the tolerable number. Do not hold the cables, axis or detector when transporting the spindle motor.
  • Page 5 (2) Wiring CAUTION Correctly and securely perform the wiring. Failure to do so could lead to runaway of the spindle motor. Do not install a phase advancing capacity, surge absorber or radio noise filter (option FR-BIF) on the output side of the spindle amplifier. Correctly connect the output side (terminals U, V, W).
  • Page 6 (5) Troubleshooting CAUTION If a dangerous situation is predicted during a stop or product fault, take prevention measures by installing an external brake mechanism to hold the tool. When an alarm occurs, always eliminate the cause of the alarm and ensure safe operation before resetting.
  • Page 7 Compliance to European EC Directives 1. European EC Directives The European EC Directives were issued to unify Standards within the EU Community and to smooth the distribution of products of which the safety is guaranteed. In the EU Community, the attachment of a CE mark (CE marking) to the product being sold is mandatory to indicate that the basic safety conditions of the Machine Directives (issued Jan.
  • Page 8 ② Connect the SJ-P and SJ-PF Series spindle motor power lead to the spindle amplifier using a fixed terminal block. Do not connect the wires directly. (5) Peripheral devices and options ① Use a no-fuse breaker and magnetic contactor that comply with the EN/IEC Standards described in section 6-2-1.
