EXTENDED REGISTER GROUPS
Int, Interrupt control
Termistor input in Motor connector event Bit 3 (bitvalue =8),
should be set if automatic trip on Motor temp high is
wanted.
In.PTC eventBit 2 (bitvalue = 4), should be set if automatic
trip on In.PTC “low” is wanted.
If no PL program is running when an event occurs, the
power stage will be shut off on the conditions specified in
Bit2, 3 and 4.
If a program is running and Vector.TempErr = 0 (default
value), the power stage will be shut of on the conditions
specified in Bit2, 3 and 4.
If Vector.TempErr 0,
the program must handle this
event by using the system interrupt on this vector, (enable
by setting bit 5 in Int.SysMask). These conditions are
checked with the rate set in SysIo.ChkTmr.
Int.TempMask is set to a default value defined in
EEprom.5, bit 4, 3 and 2 at startup, If EEprom.0 matches
the revision number of the firmware.
Bit2 (4) = 1 Enable In.PTC interrupt.
Bit3 (8) = 1 Enable interrupt on motor over temperature.
Bit4 (16) = 1 Enable interrupt on drive over temperature.
Int.BleedLim 7 0 8191 RW
Limit for bleeder monitoring.
The default value for this 0.
The function is disabled.
If set > 0 the function monitors the bleeder load,
SysIo.ADC6, with the rate set in SysIo.ChkTmr.
A value of 400 allows a load equal to 0.5 seconds of
continuous bleeding of the DC-bus.
A value of 8000 allows a load equal to 10 seconds of
continuos bleeding of the DC-bus.
If the program (interpreter) is stopped, the power stage will
be shut of when the bleeder load reaches this limit. If the
program (interpreter) is running and the
Vector.BLeedErr = 0 (the
default value), the power stage
will be shut of when the bleeder load reaches this limit.
If the Vector.BLeedErr is 0 then the
program is
supposed to handle the condition by using the system
interrupt on this vector, (enabled by setting bit 6 in
Int.SysMask).
The shunt regulator resistors can withstand a defined
amount of energy from the regenerative power stage. This
amount can be translated to a time of constant operation. A
value in this parameter of 400 is equal to 500 ms of
continuous operation. The internal resistors in the DMC 2
can be used for 500 ms continuous shunting.
Int.Mode 8 0..1 RW
=0 Normal mode. This is the default at startup.
