MAGNET POWER SUPPLY SYSTEM 9100
41
DANFYSIK A/S - DENMARK.
If synchronization to an eternal event is required, it is possible to arm the ramp sequence first
with the synchronization command “SYNC (stack no.), [trigger delay]”. A hardware signal on
the trigger input X9
pin 1&2 (10 to 24V) or a TS command will start the sequence. If a trig
delay is entered, the sequence will first start after the delay time has elapsed.
If more power supplies have to be synchronized, one of the supplies has to be appointed as
master. Connecting the master trig output X9 pin 3&4 to the other supplies trig input will start
the other supplies when the master is triggered. A maximum skew of 5μs between the supplies
may be expected. (an external 15V auxiliary supply is needed, as the trig output is an open
collector and the trig input is an optocoupler input.)

Equal time slot ramp profile method
With the ”Equal time slot method” it is possible to download up to 1000 current set values and
a single time slot value, that will be used for all set values. Only one stack is available.
This profile method is especially useable for faster and more accurate curves fitting profiles
e.g. as a function generator.
To use the Equal time slot method at least the following steps must be preformed:
- Clear and set the stack “RAMPSET [parameter]”,- Program the stack “R [parameter]”, -Start
the stack “RAMP [parameter]”, -Read the status of the running stack “RAMP".
PS.
A difference in the value parameters setting comparing to the “Arbitrary point method”
is, that all values must be given as a floating point number scaled to “1.000000". That is;
1.25ms must be entered as 0.00125 and 19.54% output current as 0.1954.
Please refer to the Software manual about Ramp Profile Commands for full instructions.
The figure below shows an example of one ramp profile stack. (Ps. not all 1000 points need to
be programmed empty entries will be ignored.)
The time slot
must be given as a multiple of 1.25ms. Between 1.25ms to 1 second. Any value in-between
will automatically be rounded according to formula:
{time slot}=frac({time}/0.00125)*0.00125
