2-26 Parameter Descriptions
7000-TD002A-EN-P – September 2007
Coast Speed [Coast Speed]
Linear Number: 60
Default Value: 2.0 Hz
Minimum Value: 1.0 Hz
Maximum Value: 100.0 Hz
Access Level: Basic
Read/Write: Read/Write
This parameter specifies the speed at which the drive stops gating and allows the motor to come to a
coast stop. For large inertia systems like ID Fan, the motor may come to a stop after a long interval of time.
Automatic Restart Delay [Auto Restart Dly]
Linear Number: 3
Default Value: 0.0 sec
Minimum Value: 0.0 sec
Maximum Value: 10.0 sec
Access Level: Basic
Read/Write: Read/Write
This parameter specifies the time interval following a line under-voltage, line loss or a control power loss
event during which the drive will automatically restart if the conditions are restored; assuming that the
drive was running at the time of the outage and the control power is maintained. This is typically done by
having a UPS feeding the power to the control boards.
Input Contactor Configuration [Input Ctctr Cfg]
Linear Number: 1
Default Value: All Faults
Access Level: Basic
Read/Write: Read/Write when Stopped
This parameter specifies the conditions under which the input contactor will be commanded to open by
the drive. The possible contactor configurations specified by this parameter are listed below.
Not Running Open the contactor when not running
All Faults Open the contactor for any fault condition in the drive
Critical Flt Open the contactor for critical faults only. For a complete list of Critical
faults refer to Appendix.
Input Contactor Open Delay [InpCtctr OpenDly]
Linear Number: 10
Default Value: 0.0 min
Minimum Value: 0.0 min
Maximum Value: 60.0 min
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the time delay between the drive shutting off, and the input contactor opening, if
the contactor is configured to open when the drive is not running. The purpose of this delay is to keep a
harmonic filter energized if the drive is stopped for a short time, and not have to wait for the filter
capacitors to discharge before restarting.
