First read the U0-60 (0x1041) value
(1)
0
means
running
in
the
positive
direction.
The
current
encoder
value
is
U0-57*1+U0-58*2^16+U0-59*2^32.
(2) 1 means running in the opposite direction. The current encoder value is: (U0-57-65535)*1+
(U0-58-65535)*2^16+ (U0-59-65535)*2^32.
Communication parameter description
RS485 default communication parameters: baud rate 19200 bps; data bit 8; stop bit 1; even parity;
Modbus station number 1.
Note: Refer to Appendix 1 (P7-XX) for communication parameter description.

1. The parameter range is 0000-0014, which is allocated to other input terminals through parameter
P5-24.
2. When an alarm occurs, find out the cause of the alarm and remove it, then clear the alarm by setting
the signal to be effective.
3. /ALM-RST signal can be assigned to other terminals through this parameter, because the alarm signal
is related to the safe operation of the servo, so the /ALM-RST signal can not be set to be always valid
(n.0010).
5.12.2 Warn output
