Operation
This parameter specifies the direction for beginning an origin search operation.
Set value
0 Begins origin search in the positive direction (incrementing the present value).
1 Begins origin search in the negative direction (decrementing the present value).
PRM No. Parameter name
PP-20 Acceleration time 0
PRM No. Parameter name
PP-21 Acceleration time 1
These parameters specify the time from a stop until the reference speed is reached.
The actual acceleration time can be obtained from the following formula:
[(Target speed – present speed) / reference speed] x acceleration time
If S-curve acceleration time (UP-14) is set, the acceleration time will be lengthened.
Acceleration time 0 is used as the acceleration time for origin search, JOG operation, and positioning
by direct input.
When positioning with PTP data, acceleration time 0 or 1 can be selected using the PTP data's accel-
eration/deceleration selection (Pd
PRM No. Parameter name
PP-22 Deceleration time 0
PRM No. Parameter name
PP-23 Deceleration time 1
These parameters specify the time from the reference speed until the positioning is stopped.
The actual deceleration time can be obtained from the following formula:
[(Present speed – target speed) / reference speed] x deceleration time
Deceleration time 0 is used as the deceleration time for origin search, JOG operation, and positioning
by direct input.
When positioning with PTP data, deceleration time 0 or 1 can be selected using the PTP data's accel-
eration/deceleration selection (Pd
