n Notes on Stationary Auto-Tuning
Stationary Auto-Tuning modes analyze motor characteristics by injecting current into the motor for approximately one minute.
WARNING! Electrical Shock Hazard. When executing stationary Auto-Tuning, voltage is applied to the motor before the motor rotates. Do
not touch the motor until Auto-Tuning is completed. Failure to comply may result in injury or death from electrical shock.
WARNING! Sudden Movement Hazard. If installed, do not release the mechanical brake during Stationary Auto-Tuning. Inadvertent brake
release may cause damage to equipment or injury to personnel. Ensure that the mechanical brake release circuit is not controlled by the
drive multi-function digital outputs.
Stationary Auto-Tuning for Line-to-Line Resistance
• Perform when entering motor data manually while using motor cables longer than 50 m.
• If the motor cables have been replaced with cables more than 50 m long after Auto-Tuning has already been performed, use
Stationary Auto-Tuning for line-to-line resistance.
