Remedy
● activate the V
– Vector control: p1240 = 1 (factory setting)
– Servo control: p1240 = 1
– U/f control: p1280 = 1 (factory setting)
● Inhibit V
– Vector control: p1240 = 0
– Servo control: p1240 = 0 (factory setting)
– U/f control: p1280 = 0
● Activate the V
– Vector control: p1240 = 4 or 6
– Servo control: p1240 = 4 or 6
– U/f control: p1280 = 4 or 6
