SmartFan® Stratus II


ISOLATED TEMPERATURE CONTROL MODE


Stratus II Variable Frequency Drive AC Motor Speed Control

Isolated Temperature Control Mode: Connection for the isolated temperature control mode is made on the Isolated I/O terminals using the COM pin for negative reference and POT pin for the temperature control.

Set registers 40001 and 40017 to 1025 (0x0401) for forward run isolated Temperature control mode.
Set register 40014 to desired ramp up rate (1Hz/Sec)
Set register 40015 to desired ramp down rate (1Hz/Sec)
Set register 40030 to 1 to save to EEPROM.

The Isolated Current Control mode is split into the following three control modes:

  • Positive Slope
  • Negative Slope
  • Two Speed

Positive Slope:
Set register 40019 to the maximum output that the motor should receive (1Hz resolution) Point A
Set register 40020 to the minimum output that the motor should receive (1Hz resolution) Point B
Set register 40025 to the temperature (-20-100°C) where the maximum output will occur. Point E
Set register 40026 to the temperature (-20-100°C) where the minimum output will occur. Point D
Set register 40027 to the temperature (-20-100°C) where the alarm will occur. Refer to register 40013 for alarms and configuration.

Negative Slope:
Set register 40019 to the maximum output that the motor should receive (1Hz resolution) Point A
Set register 40020 to the minimum output that the motor should receive (1Hz resolution) Point B
Set register 40025 to the temperature (-20-100°C) where the maximum output will occur. Point D
Set register 40026 to the temperature (-20-100°C) where the minimum output will occur. Point E
Set register 40027 to the temperature (-20-100°C) where the alarm will occur. Refer to register 40013 for alarms and configuration.

Two Speed:
Set register 40019 to the maximum output that the motor should receive (1Hz resolution) Point A
Set register 40020 to the minimum output that the motor should receive (1Hz resolution) Point B
Set register 40025 to the temperature (-20-100°C) where the maximum output will occur. Point D
Set register 40026 to the same value as register 40025.
Set register 40027 to the temperature (-20-100°C) where the alarm will occur. Refer to register 40013 for alarms and configuration.
