Rockwell Automation FlexPak 3000 Digital DC Drive Version 4.3 - Manual (Page 45)

Configuring the Speed Reference 4-25
4.4.1 Configuring Jog
For information on jog sequencing, see section 2.1, Run and Jog Sequencing.
When you use a jog input (terminals 4 and 1 on the Regulator board or pressing
), the jog signal is conditioned as shown in figure 4.7.
If DIG IN 0 SELECT (P.428) is set to JOG SPEED SELECT , you can use digital input 0
(terminals 12 and 14 on the Regulator board) to choose between two jog speeds, as
set by
JOG SPEED 1 (P.012) and JOG SPEED 2 (P.017).
When digital input 0 is:
• Off (0 V): JOG SPEED 1 (P.012) is selected.
• On (+24 V): JOG SPEED 2 (P.017) is selected.
Switching between the two jog speeds while jogging causes the drive to accelerate or
decelerate to the new jog speed at the rate set by
JOG ACCEL / DECEL TIME (P.013).
Only JOG SPEED 1 (P.012) is used if DIG IN 0 SELECT is not set to JOG SPEED SELECT .
!
ATTENTION: This drive can operate at and maintain zero speed when
either of the jog speed parameters (
JOG SPEED 1 (P.012) and JOG SPEED 2
(P.017)) is set to zero. The user is responsible for assuring safe conditions
for operating personnel by providing suitable guards, audible or visual
alarms, or other devices to indicate that the drive is operating at or near
zero speed. Failure to observe this precaution could result in severe
bodily injury or loss of life.
