Issue Number: 4
This parameter changes the functions of terminals 9, 10 and 11 which are normally associated with the enabling, starting and
stopping the drive.
Setting
6.04 from modes 0 to 3 automatically changes the functions of terminals 9,10 and 11 as in the following table. This
automatically writes to 6.40 to enable and disable the input latches as appropriate. The new value only takes effect when the
drive is reset when in disabled or tripped state.
When
6.04 is set to mode 4, the user is free to assign the terminals as appropriate to their application. Also 6.40 can be set
as required.
6.04 must be set to a 4 and saved before the destination parameters of terminals 9,10 and 11 can be reassigned.
This parameter defines the current level used for injection braking.
(For definition of
Active current limit see Menu 4: Current control).
Defines the time of injection braking for injection braking stop.
This parameter controls which direction of motor speed the drive should detect. When the motor frequency has been
detected the output frequency is started from that value and ramped towards the reference.
0 Catch a spinning motor disabled
1 Detect all frequencies
2 Only detect positive frequencies
3 Only detect negative frequencies
For the spinning motor software to function, the drive must perform a non-rotating autotune to measure a stator resistance
(see parameters
5.12 , 5.14 and 5.17 ). The drive uses this stator resistance measurement to ‘catch a spinning motor’. On the
first enable and run command of the drive from the factory, the drive will perform this autotune.
If the drive is to be set up in fixed boost mode (parameter 5.14 set to 2) an autotune must be performed before the drive is set
into fixed boost, so that a stator resistance is measured.
If the drive does not perform an autotune to measure a stator resistance, the ‘catch a spinning motor’ software will not
perform correctly and 0V or OI.AC trips will be seen. The delay time for the drive to detect the frequency of a spinning motor
and act upon it is 500mS.
