TECT_MACHINE_SET_TYPE

This structure contains machine set parameters of the zone data. User can define all parameters which are related to the machine, i.e. parameters which are set as per machine properties and will be defined only once at the time of commissioning. These parameters need to be changed only when some machine properties have changed, e.g. when a temperature sensor changed.

No Name Data Type Unit Initial Value Description Access
1 wCoolFact WORD   1000 Cool factor in percentage RW
2 rKP REAL   0 PID parameter for control P in REAL value RW
3 rTI REAL   0 PID parameter for control I in seconds RW
4 rTD REAL   0 PID parameter for control D in seconds RW
5 rT1 REAL   0 PID parameter for control filter for D in seconds RW
6 rHighHigh_Temp REAL   32767 HighHigh temperature alarm - disables all outputs RW
7 rLowLow_Temp REAL   - 32767 LowLow temperature alarm - disables all outputs RW
8 uiChange_Time UINT   0 For TC_Fault_2: time in second used to register min_temp_change when duty_cycle ³ tune_output RW
9 uiMin_Temp_Change UINT   0 For TC_Fault_2: minimum temperature change in change_time when duty_cycle ³ tune_output RW
10 rTc_Max REAL   32767 For TC_Fault_1: maximum plausible rActual_Temp RW
11 rTc_Min REAL   0 For TC_Fault_1: minimum plausible rActual_Temp RW
12 rTemp_Diff_Cool REAL   0

> 0: if temperature is temp_diff_cool higher than setpoint, then cooling is 100% ON until the temp_diff_cool*cool_off_ratio/100 over setpoint is reached.

= 0: cooling is controlled as PID

RW
13 iCool_OFF_Ratio INT   50 In percentage, if temp_diff_cool is active, see temp_diff_cool > 0 RW
14 iMax_Output INT   100 Maximum allowable duty cycle RW
15 iTune_Step INT   500 Set point change in RAW value to be reached during auto tune process RW
16 iTune_Output INT   100 PWM duty cycle used during tuning RW

19 rTune_PMult REAL   1 Scaling for KP value RW
20 rTc_Offset REAL   0 Thermocouple compensation in degree (Celsius or Fahrenheit) - if required RW
21 rPeriod_Fact REAL   10 Period factor between cooling and heating RW
22 timMin_Cool_ON TIME   t# 3 s Minimum time for which xDO_Cool output to be ON RW
23 iFF_Time_Ratio INT   125 >=100, Feedforward time ratio in percentage: for internal set point ramp generator. The smaller the value, the steeper the ramp R/W
