Chapter 5
Programming Parameters
5-38
Parameter 624 – Maintained Start [Maintain Start]
Internal units : None
Programming Terminal units: 0/1 selection
Minimum Value: 0
Maximum Value: 3
Default Value: 2
Description: Parameter 624 selects the type of Start signal required
in the logic command word. Choices are:
0 = Start signal treated as a momentary input. The drive will latch the
start input. A Stop bit will be required to unlatch the start function.
1 = Start signal treated as a maintained input. The motor will stop
should the Start bit become 0, or the Stop bit become 1.
2 = Software Coast / Regen Stop option. The start signal will be
treated as a maintained input. The Drive will Regen Stop when the
start bit is removed. The Drive will Coast Stop when the Stop bit is
set.
3= All Coast Stop option. The start signal will be treated as a
maintained input. The Drive will Coast Stop (phase back SCR firing
and open Main Contactor) under all Stop conditions:
•
Remove Start bit
•
Set Stop bit
•
Remove Jog bit
IMPORTANT: Refer to Chapter 6 – Installation, for important
information and warnings regarding stop mode interfaces with the
1395.
Parameter 625 – Torque Mode [Torque Mode]
Internal units : None
Programming Terminal units: 0/1 selection
Minimum Value: 0
Maximum Value: 5
Default Value: 1
Description: Parameter 625 selects the torque command source
within the Drive. Choices are:
0 = Zero torque command under all conditions.
1 = Velocity regulator output
2 = External torque reference comes from parameters 157 (Torque
Reference).
3 = Minimum select of 1 & 2. Selecting this function will
automatically connect this algebraic minimum of either the velocity
regulator output or the external torque reference to the torque mode.
4 = Maximum select of 1 & 2. Selecting this function will
automatically connect the algebraic maximum of either the velocity
regulator output or the external torque reference to the torque mode.
5 = Load Response (sum of 1 & 2). Selecting this function will
automatically take the algebraic sum of the velocity regulator output
and the external torque reference to the torque mode.
