Maximum speed [BFM #14009, #14008, BFM #14209, #14208]
This parameter sets the maximum speed for each operation.
→
For details on the maximum speed, refer to Section 7.2
*1.
Refer to the section shown below for details on the user units and converted pulse data.
→
Refer to Section 7.10
Note
Set JOG speed, zero return speed (high speed), zero return speed (creep), operation speed 1 and operation
speed 2 at or below the maximum speed. If the operation speed exceeds the maximum speed, the 20SSC-H
operates at the maximum speed.
Cautions in setting
Set the maximum speed at or below the maximum rotation speed of the servo motor.
The formula to calculate the rotation speed of the servo motor from the pulse (Converted pulse data) is as
follows.

11.1.6
JOG speed [BFM #14013, #14012, BFM #14213, #14212]
This parameter sets the speed for Forward JOG and Reverse JOG operations.
→
For details on the JOG operations, refer to Section 8.2
*1.
Refer to the section shown below for details on the user units and converted pulse data.
→
Refer to Section 7.10
Note
• Set the JOG speed at or below the maximum speed.
When the JOG speed exceeds the maximum speed, the 20SSC-H operates at the maximum speed.
• Speed change commands in positioning operation change the JOG speed into a preset value.
11.1.7
JOG Instruction evaluation time [BFM #14014, BFM #14214]
This parameter sets the evaluation time for the forward/reverse JOG command to determine whether the
control is inching or continuous.
For forward/reverse commands that are ON for longer than the JOG evaluation time, the 20SSC-H executes
continuous operation. For forward/reverse commands that are ON for shorter than the JOG evaluation time,
the 20SSC-H executes inching operation.
→
For details on the JOG operations, refer to Section 8.2
POINT
The JOG instruction evaluation time “0 ms” gives continuous operation only.
