5) Steuerhardware und Hardware-Konfiguration der I/O Steuerkanäle
Digital output channels:
Inverters of the E800 series, SIZE
both are free programmable for different functions, assignation codes are set in parameters F300 – F302.
TA-TB-TC Relay output: isolated switch over contacts, max. contact-load: 5A 230V (F300)
DO1 Digital output: OPEN COLLECTOR, referred to CM - U/High=24V, max. sink-current 100mA. (F301)
DO1 may work as fast pulse signal output too, set via parameter F303 max. frequency 50 kHz, U
DO2 Digital output: OPEN COLLECTOR, referred to CM - U/High=24V, max. sink-current 100mA (F302).
Analogue output channels:
Two analogue output channels are available on inverters E800 SIZE
mapped to both channels
AO1
: To configure via hardware for voltage or current signal mode – signal configuration via parameter 423-426, function
assignation code in parameter F431
Hardware configuration is necessary for
(voltage/current mode selection)
AO2
: Output for current signal only – function assignation code: F432
Motor protection with PTC/KLIXON: Valid for all inverter size
For simple applications and short motor cables (<5m) the digital inputs OP1...OP6 (8) can be used as PTC/NTC/KLIXON signal
input channel.
For hardware set-up, see picture below, the value of the resistor depends on the PTC value, if KLIXON is used for motor
protection, a 1 kOhm resistor, 1 WATT is recommended. Each digital input is programmable for PTC/KLIXON signal evaluation
The trigger threshold is about 4 V – it means about 20V input signal level for PNP configuration - about 4V input signal level for
NPN configuration.
OH1
If triggered,
is the error code shown on the display
Function assignation parameter F316...F323:
code: 37 for normal open contact (NTC)
code: 37 for normal closed contact (PTC)
ATTENTION!!! Provide adequate
insulation between
and motor phases
