To recover from this situation, you must switch on the encoder power,
reset and home the axis.
7. EncGND is connected to the internal system ground, which is ground
MCU, drive logic, analog I/O, and host PC if the MCU is NY4110 and an
IEEE 1394b cable is used.
For proper use, this ground may not be connected to motor or digital I/O
ground.
13.14 NY4199 SinCos Option module for SinCos based encoders
13.14.1 Overview
All drive modules discussed in previous chapters, except the NY4125 and
NY4150, have sockets for the NY4199 SinCos Option module. The NY4199
SinCos Option module is directly connected onto the drive module. Part
number is R911320450, ordering code is NYM04.1-ESC-NNNN-NY4199.
Fig. 13-30:
SinCos Option module NY4199
Main features of the NY4199 SinCos Option module are the following.
●
Installed directly on the drive module
●
Power consumption approximately 1.25 W at 24 V system power supply
voltage (power supply required for connected encoders not included)
Via the connectors the NY4199 SinCos Option module has three differential
signal interfaces (Opt_0, Opt_1 and Opt_2) to the on-board logic. On the
drive modules there are three additional differential signals (Dig5VIn1a,
Dig5VIn1b and Dig5VIn1c) routed to the NY4199 SinCos Option module.
This is shown schematically in
