Motor.BaseSpeed
15 0..32767000 RW
The motor speed in inc/sec where field weakening starts.
Motor.MedSpeed 16 0..32767000 RW
When abs( RD1.Speed) is above Motor.MedSpeed then a
linear reduction of Motor.ATorqPLim and
Motor.ATorqNLim is performed.
For induction motors the Motor.ATorqPLim and
Motor.ATorqNLim is used instead of REG.TorqPLim and
REG.TorqNLim.
Motor.HighSpeed 17 0..32767000 RW
When abs( RD1.Speed) >= Motor.HighSpeed. Both
Motor.ATorqPLim and Motor.ATorqNLim is set to zero.
Motor.ATorqPLim 18 -8192 8191 RW
The actual positive torque limitation used in the induction motor
regulator. See Motor HighSpeed, Motor.MedSpeed and
Motor.BaseSpeed.. To set this limit, use REG.TorqPLim.
Motor.ATorqNLim 19 -8192 8191 R
The actual negative torque limitation used in the induction
motor regulator. See Motor.HighSpeed, Motor.MedSpeed
and Motor.BaseSpeed. To set this limit, use REG.TorqNLim.
Motor.Temp 20 -32768 32767 RW
i
The value from an ANA.Inx analog input.
The value in
Motor.Temp is the motor winding temperature and is used
for slipgain temperature compensation.
The selected analog input must be adjusted, using
ANA.InxRange and ANA.InxOffs, so that the temperature,
for which the Motor.SlipGain was given
as motor
parameter, result in a 0 reading at Motor.Temp.
The ANA.Inx should be copied to the Motor.Temp at least a
few times but that depends on the thermal time constant of
the motor. The Slipgain will be adjusted according to the
formula:
1. Connect Ana.Inx to Motor.Temp
Ana.ConnTMR, 200
2. Let Motor.Temp, Ana.Inx

Two ways of doing this are:
If any more Connect statement is to be used, and with
much lower Ana.ConnTMR setting the second way is
prefered. But be sure that the code is executed often
enough.
