k_witt Posts: 3 Rating: (0)	I have a question on how to increase value of P0640 (Motor overload factor) of inverter V20. The range of P0640 as shown in the manual is 10-400(%). The P0640(index 0) value in my inverter is 100 that I can decrease, but I cannot increase more than 100. Please help me check how to increase the value of P0640.

Please help me check how to increase the value of P0640. Kindly find the attached file. P0640 Defines motor overload current limit relative to P0305 (rated motor current). Dependency: Limited to maximum inverter current or to 400 % of rated motor current (P0305), whichever is the lower. P0640_max = (min(r0209, 4 * P0305) / P0305) * 100 Attachment P0640.pdf (780 Downloads)
