Factory Setting (NPN mode)
+24V ± 10 % 100 mA
Refer to parameters 02-01~02-07 to program the
multi-function inputs MI1~MI7.
Source Mode
ON: the activation current is 3.3 mA ≧ 11Vdc
OFF: cut-off voltage ≦ 5Vdc
Sink Mode
ON: the activation current is 3.3 mA ≦ 13Vdc
OFF: cut-off voltage ≧ 19Vdc
 When Pr. 02-00=0, MI1 and MI2 can be programmed
 When Pr. 02-00≠0, the function of MI1 and MI2 is acc.
to Pr02-00 setting.
 When Pr02-07=0, MI7 is pulse input with max.
frequency 33kHz (See Pr. 10-00, Pr. 10-02, Pr. 10-16)
DFM is a pulse-signal output; Duty-cycle: 50%
Min. load impedance R
Max. current: 30mA
Max. capacitive load: 100pF
Max. voltage: 30 Vdc ± 1 %
(when 30 Vdc / 30 mA /R
Max. output frequency: 33kHz
Internal current limiting resistor R: ≧ 1KΩ
Output load impedance R
Capacitive load≦100 pf
Resistive load≧1 kΩ，resistance determine the output
voltage value.
DFM-DCM voltage = external voltage * ( R
Programmable open-collector outputs, see Pr. 02-16 and
Pr. 02-17.
Max 48 Vdc 50 mA
Programmable relay output, see Pr. 02-13.
