Input / Output 4-7MN19024.3.2 CREF and digital inputsPin 7 (CREF) controls the sense of all the digital inputs (X3 pins 9 to 17) and should bepermanently wired, dependent on the user requirements:Active high: connect 0V to pin 7.The digital inputs will be active when a voltage of +24VDC (greater than 12VDC) is applied tothem and will sink a current of approximately 5mA each.Active low: connect +24VDC to pin7.The digital inputs will be active when grounded (less than 2V) and will source a current ofapproximately 5mA each.The +24VDC supply is from a customer supplied 24VDC supply that should have a continuouscurrent capability of 1.75A.The sense of the inputs can be configured in WorkBench v5 or controlled individually in Mintusing the keyword INPUTACTIVELEVEL.See section 3.8 for more information about Drive Enable.4.3.3 Special functions on DIN4 and DIN5 - pulse and direction inputsDIN4 and DIN5 can be configured using the MASTERSOURCE keyword to behave as pulseand direction inputs:H DIN4 is used as the pulse input. The pulse frequency controls the speed of the motor.H DIN5 is used as the direction input. The state of the direction input controls the direction ofmotion. A positive voltage will result in forward motion. If DIN5 is grounded, movement willbe in the opposite direction.Note: If DIN4 and DIN5 have been configured as pulse and direction inputs, thealternative pulse and direction inputs, available on connector X9, cannot be used.See the Mint keyword MASTERSOURCE.
