MODBUS RTU communication stop bit

NOTE
• For the details of the MODBUS RTU protocol, refer to 5.15.6 MODBUS RTU communication specification of the
Instruction Manual (Detailed).

Direct JOG function
 JOG forward rotation command (JOGF) and JOG reverse rotation
command (JOGR) signals, Pr.15, Pr.16, Pr.178 to Pr. 189
• While the JOGF or JOGR signal is input, the Pr.15 Jog frequency setting is used for operation. The rotation is forward
while the JOGF signal is input, and the rotation is reverse while the JOGR signal is input.
• Use Pr.16 Jog acceleration/deceleration time to set the acceleration/deceleration time during JOG operation.
• For each signal, refer to the following table and assign the function by Pr.178 to Pr.189 (input terminal function
selection) .
NOTE
• When the JOGR or STR signal is input while the JOGF signal is input, the motor is decelerated to stop.
• When the JOGF or STF signal is input while the JOGR signal is input, the motor is decelerated to stop.
• The three-wire type connection is not available for the JOGF and JOGR signals.
• When the MODBUS RTU communication protocol is selected, the stop bit length without parity check can be selected
between 1 bit and 2 bits.

Without parity check
The stop bit length is selectable between 1 bit and 2 bits
(according to
Pr.333 ).

With parity check at odd numbers
Stop bit length 1 bit
2
With parity check at even numbers
Stop bit length 1 bit
• The JOG forward rotation command (JOGF) and JOG reverse rotation command (JOGR) signals are now available for
the setting of the input terminal function selection.
• By turning ON the JOGF or JOGR signal, JOG operation can be started using Pr.15 Jog frequency and Pr.16 Jog
acceleration/deceleration time without turning ON the start signal (STF or STR).
