VS-616G5 Programming Manual

Setting Range:

0 to 100%

Factory Default:

1%

This parameter sets the level at which a loss of PID feedback is detected. The PID feedback must be at
or below this level for the time defined by B5-14 before a loss of feedback can be detected. A setting
of 100% represents 100% of the feedback signal.

Setting Range:

0.0 to 25.0

Factory Default:

1.0

This parameter sets the gain of the PID output. The PID output can be monitored by parameter U1-37
PID Output Monitor.
Refer to PID Block Diagram Figure 9.

Reference Hold
The reference hold or dwell function is used to temporarily hold the output frequency at a set refer-
ence, for a set time, and then start it again. This function can be used when driving a permanent magnet
motor, or a motor with a heavy starting load. This pause in acceleration allows the magnets in a perma-
nent magnet motor to synchronize with the stator field of the motor, thus reducing traditionally high
starting current.

Setting Range:

0.0 to 400.0Hz

Factory Default:

0.0Hz

Sets the dwell frequency reference during acceleration in units of 0.1Hz.

Setting Range:

0.0 to 10.0s

Factory Default:

0.0s

Sets the amount of time that the frequency reference “dwells” during acceleration in units of 0.1s.

Setting Range:

0.0 to 400.0Hz

Factory Default:

0.0Hz

Sets the dwell frequency reference during deceleration in units of 0.1Hz.
