Chapter 6 Control Terminals MS300 (High Speed Model) 6-3 Terminals Terminal Function Factory Setting (NPN mode) +24V Digital control signal common (Source) +24V ± 10 % 100 mA MI1 ~ MI7 Multi-function input 1~7 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 ≥ 11 VDC OFF: cut-off voltage ≤ 5 VDC Sink Mode ON: the activation current is 3.3 mA ≤ 13 VDC OFF: cut-off voltage ≥ 19 VDC 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 Pr. 02-00 setting. When Pr. 02-07=0, MI7 is pulse input terminal.
MI7 uses pulse input, the maximum input frequency = 33 kHz, can be used as frequency command source or connected to the encoder as motor closed loop control. MI7 motor closed loop control only supports VFPG control mode. DFM Digital frequency meter DFM DCM DFM is a pulse-signal output; Duty-cycle: 50 % Min. load impedance R : 1 kΩ / 100 pf L Max. current: 30 mA Max. capacitive load: 100 pF Max. voltage: 30 VDC ± 1 % (when 30 VDC / 30 mA /R = 100 pf) L Max. output frequency: 33 kHz Internal current limiting resistor R: ≥ 1 KΩ Output load impedance R L Capacitive load ≤ 100 pf Resistive load ≥1 kΩ，resistance determine the output voltage value.
