STOP!
Use only 10 V (peak to peak) or less resolvers. Use of higher voltage
resolvers may result in feedback failure and damage to the resolver
option module.
4.1.9 P12 - Second Encoder Interface Module (option)
PositionServo drives can support a second incremental encoder interface for dual-loop
systems. Depending on the motor’s primary feedback type (encoder or resolver) a
second encoder can be connected as follows:
• If the primary motor feedback is an encoder (connected to P4), the second
encoder interfaces through the encoder option module (E94ZAENC1) at P12 on
Option Bay 2.
• If the motor primary feedback is a resolver connected to the resolver option
module (E94ZARSV1) at P11 on Option Bay 2, the second encoder connects to
the P4 connector on the drive. In this case, the hall inputs on P4 are not used.
The 2nd Encoder Option Module includes a 9 pin D-shell male connector. When using
a Lenze motor with encoder feedback and a Lenze encoder cable, the pins are already
configured for operation. If a non-Lenze motor is used, the encoder connections are
made as follows:
P12 PIN ASSIGNMENTS (Second Encoder Feedback)
Pin Name Function
1 E2B+ Second Encoder Channel B+ Input
2 E2A- Second Encoder Channel A- Input
3 E2A+ Second Encoder Channel A+ Input
4 +5v Supply voltage for Second Encoder
5 COM Supply common
6 E2Z- Second Encoder Channel Z- Input
7 E2Z+ Second Encoder Channel Z+ Input
8 N/C No Connection
9 E2B- Second Encoder Channel B- Input
The second encoder needs to be enabled using MotionView software. Refer to “Dual-
loop Feedback” (Section 6.4) for details.
STOP!
Use only +5 VDC encoders. Do not connect any other type of encoder
to the option module otherwise damage to drive’s circuitry may result.
