Hitachi WJ200 Series

3−49
Electronic thermal characteristic curve: The characteristic curve depends on dual rate
setting in b049 as follows.
Electronic thermal characteristic: The characteristic curve is unique, but reduction
rate depending on frequency is selected in b013.
• Reduced Torque (b013=00)
• Constant Torque (b013=01)
Example: WJ200-015L**, Base FQ=60Hz, ND setting (Rated current 9.6A= b012)
