(15) Carrier frequency upper/lower limit, proportion gain (Cn-23 to Cn-25)
• The relationship between output frequency and carrier frequency is determined as
follows from the set values of Cn-23 to Cn-25.
(a)
For constant carrier frequency (set value of Cn-23):
• Set 0 in Cn-25 and set the same value in Cn-23 and Cn-24.
(b)
For variable carrier frequency: Carrier frequency changes according to Cn-23 to 25
set values and output frequency as shown below.
Invalid Fc (OPE11) is displayed in the following cases:
1 Cn-25 > 6 and Cn-24 > Cn-23
2 Cn-23 > 5kHz and Cn-24 ≤ 5 kHz
(16) Overtorque detection level (Cn-26)
• Set overtorque levels in units of 1%. AC drive rated current is regarded as 100%.
(17) Overtorque detection time (Cn-27)
•
Set overtorque detection times in units of 0.1 second.
(18) Stall prevention level during acceleration (Cn-28)
• Set stall prevention level during acceleration in units of 1%. AC drive rated current is
regarded as 100%.
(19) Stall prevention level during run (Cn-30)
• Set a level for stall prevention level during run in units of 1%. AC drive rated
current is regarded as 100%
• Stall prevention during run starts deceleration when the output current is greater than
the setting value of Cn-30 (stall prevention level during run) for during agreed frequency for
100ms or more. The AC drive decelerates as long as the output current exceeds the setting
value of Cn-30 (stall prevention level during run). When the output current goes below the
setting value, the AC drive reaccelerates. The deceleration time selected in the 4th digit of
Sn-10 is used.
• During stall prevention during run, stall prevention during deceleration and acceleration
are still enabled.
