Operating the Drive 4-27
DC590+ Series DC Digital Drive
Advanced Starting Methods
Starting Several Drives Simultaneously
1. Apply 24V to Terminal C3 (Start)
2. Use Terminal C5 (Enable) to synchronise the start-up of the Drives
Jog
NOTE The Drive will not start if there are alarms present.
This facility provides two dedicated jog setpoints (or perhaps an Inch Forward/Inch Reverse). Activating Jog runs the
motor at speeds set by JOG SPEED 1 or JOG SPEED 2. The JOG/SLACK::MODE parameter selects JOG SPEED 1 or 2.
1. Apply 24V to Terminal C5 (Enable)
2. Apply 24V to Terminal C4 (Jog Mode)
Refer to Appendix D: “Programming” - JOG/SLACK for further information. Also refer to the STOP RATES function
block: the CONTACTOR DELAY parameter is used to prevent multiple operations of the main contactor from rapid use of
the Jog switch.
Crawl
NOTE The Drive will not start if there are alarms present.
This facility provides a dedicated crawl setpoint. Activating Crawl runs the motor at the speed set by CRAWL SPEED.
1. Apply 24V to Terminal C5 (Enable)
2. Set JOG/SLACK::MODE parameter (Tag No. 228) to TRUE.
3. Apply 24V to Terminal C3 (Start) and Terminal C4 (Jog Mode) simultaneously to start the Drive using the crawl
speed, in Forward or Reverse.
When selecting CRAWL, apply Start (C3) and Jog (C4) simultaneously, otherwise you may experience Modes 3 or
6 momentarily. Refer to Appendix D: “Programming” - JOG/SLACK for further information (see the Setpoint
Selection Table).
