    All manuals and user guides at all-guides.com NOTES FOR SAFE OPERATION Read this instruction manual thoroughly before installation, operation, maintenance or inspection of the VS mini. In this manual, NOTES FOR SAFE OPERATION are classified as “WARNING” or “CAUTION”. WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury to personnel.
  • Page 6 All manuals and user guides at all-guides.com MOUNTING CAUTION (Ref. page) • Lift the inverter by the cooling fin. When moving the unit, never lift by the plastic case or the terminal covers. Failure to observe this caution may cause the unit to be dropped resulting in damage to the unit.
  • Page 7 All manuals and user guides at all-guides.com WARNING (Ref. page) • For 400V class, make sure to ground the supply neutral. • Make sure to ground the ground terminal according to the local ground code. Failure to observe this warning can result in electric shock or fire.
  • Page 8 All manuals and user guides at all-guides.com OPERATION WARNING (Ref. page) • Only turn ON the input power supply after replacing the digital operator or optional blank cover. Do not remove the digital operator or the covers while current is flowing. Failure to observe this warning can result in electric shock.
  • Page 9 All manuals and user guides at all-guides.com CAUTION (Ref. page) • Never touch the heatsink or braking resistor, the temperature is very high. Failure to observe this caution can result in harmful burns to the body. • Since it is easy to change operation speed from low to high speed, verify the safe working range of the motor and machine before operation.

  • Page 91 All manuals and user guides at all-guides.com • Preventing Motor from Stalling (Current Limit) This function automatically limits the output current in response to load changes by adjusting the output frequency to prevent motor stalling. • Stall prevention (current limit) level during acceleration (n56) Sets the stall prevention (current limit) level during acceleration in units of 1% (Inverter rated current = 100%).
  • Page 92 All manuals and user guides at all-guides.com • Stall prevention (current limit) level during running (n57) Sets the stall prevention (current limit) level during running in units of 1% (Inverter current = 100%). Factory setting: 160% A setting of 200% disables the stall prevention (current limit) during running. If the output current during speed agree exceeds the value set for n57 for longer than 100msec, deceleration starts.
