Example
Basic requirements:
• DS7 soft starter: rated motor current = 55 A
• Motor: rated motor current = 41 A
• Current measurement with measuring range of 0 - 400 A
Calculation:
• Writing to PNU 290.0 with I = 41 A
• Measured current: 82 A
• Scaling on PNU 290.0 = 41 A ￫
I
rel
= 82 A / 41 A ≙ 200 % ≙ 0x4000
• Value transmitted to DS7 soft starter: 0x4000
