you use an Open Collector encoder (e.g. E6B2-CWZ6C) at 24 V with 10 m cable,
you can typically generate count pulses up to 20 kHz. Therefore, if you want to
generate count pulses with higher frequencies, you should use a different type of
encoder (e.g. E6B2-CWZ1X with Line Driver output or a fast push-pull 24 V
encoder, e.g. E6C2-CWZ5GH) or reduce the length of the encoder cable.

Note 1. Every Digital Output has 2 Output drivers available: NPN and PNP (available
as separate pins on the front connectors). Every Output can be separately (DM-)
configured for NPN or PNP. By default the Outputs are configured as NPN-output
(refer to 3-5-4 "Output Control Configuration").
2. The Digital Outputs are insulated from the I/O-bus but not from each other.
They are not short circuit protected.
3. The Output current must not exceed 200 mA per common (i.e. per 2 Digital Out-
puts) otherwise the unit will be damaged.
4. The Outputs can be automatically or manually controlled (DM-setting) by using
Force ON/OFF bits in CIO (refer to 3-5 "Output Control").
5. The state control of the Outputs, in case the operating mode of the PLC-CPU
is changed from RUN/MONITOR → PROGRAM, an I/O Bus error or an Over-
flow/Underflow error occurs, can be configured (refer to 3-5-4 "Output Control
Configuration").
