ANALOG OUTPUT 2
(TERMINAL 11) FUNCTION
SELECT
Selects the type of output signal information indicated from terminal 11.
Note :
When using settings 0 – 7 the output is a digital format (Logic 1 = 24V).
When using settings 8– 11 the output is an analog format.
Note : When using settings 4 – 7, parameters 3203 ADJUSTABLE THRESHOLD 1 UPPER LIMIT
and 3202 ADJUSTABLE THRESHOLD 1 LOWER LIMIT must be used together to control the
behaviour. The output will switch to Logic 1 when the selected signal exceeds the value
programmed in parameters 3203 ADJUSTABLE THRESHOLD 1 UPPER LIMIT, and return to
Logic 0 when the signal falls below the value programmed in 3202 ADJUSTABLE THRESHOLD
1 LOWER LIMIT.

20 LIMITS
Drive operation limits
2005
OVER VOLTAGE CURRENT
LIMIT
This parameter is only valid in vector speed control mode and will come into function once
the drive DC bus voltage increases above a preset limit
This voltage limit is set internally just below the over voltage trip level. This parameter will
effectively limit the output torque current in order to prevent a large current flowing back to
the drive, which may cause an Over-voltage trip. A small value in this parameter will limit the
motor control torque when the drive DC bus voltage exceeds the preset limit. A higher value
may cause a significant distortion in the motor current, which may cause an aggressive,
rough motor behaviour.
