AMI Analog current output 0-20mA (4-20mA DC) current output. Permissible load impedance below 250Q
TH External thermistor Input terminal When an external thermistor (either PTC or NTC types, selectable by b098) is connected and the resistance measured reflects abnormal temperature level, the inverter will trip (if enabled). The thermistor connect between TH and CM1. Electric thermistor power: 100mW or more. Default impedance for temperature alarm: 3kQ (but the level for the temperature alarm can be adjusted between 0-9999Q by b099). Range of permissible input voltage: 0 to 8VDC Input circuit:
Digital Pulse output FM Digital voltage monitor 0-10V digital output working as PWM output (duty cycle control) for most inverter monitors, except for C027=03 (Digital Output Frequency), it becomes frequency output. Maximum output current of 1.2mA. The maximum frequency is 3.6kHz.
Power supply P24 24VDC power supply terminals for digital inputs 24VDC power supply for the digital inputs. When source logic is selected, it becomes the common point of inputs. Permissible maximum output current 100mA.
CM1 0V terminal for digital inputs supply 0V terminal for 24VDC (P24) power supply terminal, thermistor input (TH) terminal and the FM terminal. When the sink logic is selected, it becomes the common point of inputs. Note: Do not connect to ground earth.  
Digital Contact input 1 2 3 4 5 6 7 GS1 GS2 Multifunction input terminal It is possible to allocate any of the digital multifunction inputs to this terminals. When safety inputs GS1 and GS2 are enabled by hardware dip-switch SW1, multifunction settings 78: GS1 and 79: GS2 are compulsory. When safety inputs are disabled, GS1 and GS2 can be used as standard multifunction inputs. Minimum ON voltage: 18VDC Input impedance PLC-input: 4.7kQ Maximum ON voltage: 27VDC Input load: 5.6mA at 27VDC
PLC Digital inputs common This terminal is used as the common terminal of the digital inputs. For internal supply (and voltage-free contacts): Short between P24 and PLC: Sink logic (the current will flow from the LX input to the output) Short between CM1 and PLC: Source logic (the current will flow from the output to the LX input)
