Note:
The range of the
PULSE LEVEL
can be extended
to
70-700% even if
PULSE
TIME≥1SEC. by
using the
EXTENDED
SETTING as
described in
section 6.4.4
page 42.
Sets PULSE LEVEL and PULSE START TIME.
Intended to break free high friction loads requiring high
starting torque for a short time or for pedestal start by holding
the current at a predefined level for predefined time period.
The pulse is defined by its current level and time length
(width).
After this pulse the voltage is ramped down to INITIAL
VOLTAGE setting before ramping up again to full voltage
according to the START PARAMETERS settings.
For PULSE TIME<1SEC. PULSE LEVEL can be set to 70-
700% of FLA;
For PULSE TIME≥1SEC. PULSE LEVEL can be set to 70-
400% of FLA; In EXTENDED SETTING (refer to section 6.4.4
page 42) PULSE LEVEL can be set to 70-700% with the
limitation of: 440x(FLC/FLA).
Notes:
PULSE START is not effective in SOFT START CURVE 0.
For better control of the current withdrawn from the
network (mainly from generators), the following settings
applies (applies from software versions newer than
MVSTMB.GN-010509):
