(2)  Instantaneous resistance of dynamic brake 
When the load inertia (JL) substantially exceeds the applicable load inertia, dynamic brake resistance 
may abnormally increase, causing an overheating alarm or damage of the dynamic brake resistance. 
Consult with us if such operating conditions are assumed. 
The energy E

9.1.16 Regenerative Processing 
Although the PY2 (15 A/30 A) has a built-in regenerative processing circuit, no regenerative resistor is 
provided.    So, externally connect a regenerative resistor as necessary.    It is recommended that one be 
externally connected when a 300 W or higher motor is to be driven. 
Mount it between the P and Y (or COM) terminals of connector CND on the front of the amplifier.     
The PY2 (50 A) has a built-in regenerative resistor.   However,...
