Rexroth Frequency Converter EFC x610
Series
Fig. 12-29: Temperature sensor with current supply
Activate the function of temperature monitoring with temperature sensor:
Parameter [E1.60] 'Motor temperature sensor channel' is used enable to the pro-
tection with sensor.
Select the sensor type:
[C1.72] = 0: KTY84/130
●
For KTY84/130 sensors, the value of resistor R in the figure should be close to
the sensor resistance when the motor is at high temperature.
[C1.72] = 2: PT100
●
For a good resolution of temperature with PT100 sensors, the value of resis-
tor R in the figure should be close to the sensor resistance at the motor tem-
perature limit.
[C1.72] = 3: PT1000
●
For PT1000 sensors, the relationship between the resistor R and the motor
temperature is:
-30 ℃: 882 Ω
0 ℃: 1,000 Ω
200 ℃: 1,758 Ω
[C1.72] = 4: TDK G1551_8320 (NTC)
●
Supply source to the temperature sensor:
If [E2.26] = '11: Motor temperature sensor power supply' (or [H8.26] = 11),
●
the analog output is shifted with current supply mode regardless of the set-
ting of E2.25 (or H8.25). In this case, the output current on the selected ana-
log output terminal is:
– [C1.72] = 0, output current = 1.6 mA
– [C1.72] = 2, output current = 9.1 mA
– [C1.72] = 3, output current = 1 mA
– [C1.72] = 4, output current = 4 mA
If [E2.26] ≠ 11, the AO output mode is resumed to [E2.25] 'AO1 output mode'
●
automatically.
