Internal DB
TransistorProtection
Sets the protection function for the internal braking transistor.
1
(0, 1)
0 : Disable
Disables braking transistor protection.
Use this setting, if enabling the braking transistor can cause an
rF [Braking Resistor Fault]
in these conditions:
•
With a regenerative converter, for example D1000.
•
With a regenerative unit, for example R1000.
•
When connecting braking resistor options to the drive, for example CDBR units.
•
Without an internal braking transistor.
1 : Protection Enabled
Prevents damage to the internal braking transistor when using a braking transistor or optional braking resistors.
These models have a built-in braking transistor:
•
2004 to 2138
•
4002 to 4168

Stall P @ Accel
Activation Time
Sets the length time that the acceleration stall prevention function can
continue to operate before the drive detects an
STPo [Desynchronization
Error]
.
5000 ms
(100 - 5000 ms)
Note:
If this value is too small, it can cause incorrect detection of
STPo
. If this value is too large, the drive will not detect
STPo
.
