5.8 Wiring of digital frequency input / digital frequency output
Technical data
Field Digital frequency output X10
Connection at drive controller Connector: female, 9−pole, Sub−D
Pin assignment Dependent on the selected basic configuration
Output frequency 0 ... 500 kHz
Signal Two−track with inverse 5 V signals (RS422) and zero track
Load capacity Max. 20 mA per channel
(up to 3 slave drives can be connected)
Special features The "Enable" output signal at X10/8 switches to LOW if the drive
controller is not ready for operation (e.g. disconnected from mains). This
may trip SD3 monitoring on the slave drive.
Internal voltage source
(X10/4, X10/5) DC 5 V / max. 50 mA
Total current at X9/4, X9/5 and X10/4, X10/5: max. 200 mA
Field Digital frequency input X9
Connection at drive controller Connector: male, 9−pole, Sub−D
Input frequency TTL level: 0 ... 500 kHz
HTL level: 0 ... 200 kHz
Signal Two−track with inverse signals and zero track
Two−track without inverse signals and zero track (only for HTL level)
Signal evaluation Via code C0427
Current consumption Max. 5 mA
Special features With activated SD3 monitoring, TRIP or warning is tripped if the "Lamp
Control" input signal at X9/8 switches to LOW.
Due to this the drive controller may respond if the master drive is not
ready for operation.
