2.2 List of parameters
Description:
Sets the signal source for variable control of the armature current controller's integral time.
Note:
The integral time (Tn) for the armature current controller is calculated as follows:
Tn = p50156 x |p50176|
Description:
Sets the signal source for the "No immediate pulse inhibit" command.
A low signal will cause the armature firing pulses to be inhibited immediately without waiting for the I = 0 signal or
sending Alpha W pulses for current decay. The additional Alpha W pulses (as set in p50161 and p50179) are not
output either. As long as this command is pending, it will not be possible to switch to an operating state lower than
o1.6.
Note:
This command can be used, for example, if the drive is being used to supply a field rather than a motor and the
current is to be reduced via an external built-on field discharge resistor connected in parallel.
Description:
Sets the signal source for the "Fire all thyristors simultaneously" command.
The default setting of this command (high signal) causes all 6 thyristors on thyristor bridge I to be fired continuously
and simultaneously. Changeover to long pulses is automatic.
Note:
However, this command is only active if no line voltage is applied to the armature power unit.
Description:
Sets the additional Alpha W pulses with enabled second pulse in the auto-reversing stage.
Recommendation:
This parameter should be set to values > 0 in particular when supplying high inductances (e.g. infeed of solenoids).
Note:
Number of additional Alpha W pulses with enabled second pulse following detection of I = 0 signal prior to a change
in torque direction.
These pulses cause the current to decay before a change in torque direction; the thyristors are fired in pairs to
prevent sudden chopping and the generation of overvoltage by the load inductance when the current drops below the
thyristor holding current.
When a change in torque direction is required, the current in the existing direction must be reduced.
