Speed control error function usage selection (F-30):
In the Speed control error function usage selection (F-30), you can select whether speed control error
protection is enabled or not.
Speed control error detection speed width (positive) (F-31), speed control error detection speed width
(negative) (F-32):
The speed control error detection speed width (positive) (F-31) and speed control error detection speed width
(negative) (F-32) become the maximum speed (A-00) when set to 100%.
・
When the speed control error function usage selection is set to function active (F-30 = on)
The speed deviation is acquired with the following expression:
Speed deviation = speed command - speed
When the speed deviation > (maximum speed (A-00) x speed control error detection speed width
(positive) (F-31) (%))
or
the speed deviation < (maximum speed (A-00) x speed control error detection speed width (negative)
(F-32) (%)),
a speed control error (SPdE) occurs and protection detection is performed.
This is activated when the speed controller or PG is abnormal or the speed is reduced due to the load
current exceeding the current limit.
When the operation mode selection is speed control (i-07 = 1), the speed command is a speed command
selected in the speed command input (b-10). Otherwise, the speed command is the input from analog
input (1) [VFC66-Z TB1] (AIN1) (0 to ±10 V voltage input, 0 to +10 V voltage input).
・
When the speed control error function usage selection is set to function inactive (F-30 = oFF)
A speed control error does not occur.
