Items related to speed

The following describes the setting items related to speed.
Command speed
Setting method: Operand
Set the speed used in positioning operation. The user unit is set by unit setting. (Page 50 Unit Setting)
The setting range differs depending on the positioning instruction and table operation control method. Set the command
speed to 200 Kpps or lower in pulse (-200 Kpps to +200 Kpps for the PLSV/DPLSV instruction or table operation instruction
(control method: [4: Variable Speed Operation], [5: Table Transition Variable Speed Operation])).
Even within the setting range, the following relation must be followed: bias speed ≤ command speed ≤ maximum speed.
When command speed is faster than the maximum speed, the maximum speed is applied. When positioning instruction start,
if bias speed is faster than command speed, the bias speed is applied.
