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.

Output Specifications
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 400 mA per common (i.e. per 4 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
).
5. The state control of the 32 Outputs, in case the operating mode of the PLC-
CPU is changed from RUN/MONITOR
→
PROGRAM, an I/O Bus error or an
Overflow/Underflow error occurs, can be configured (refer to 3-5-4
).
