Chapter 4: Operating Procedure
For set values other than the mode settings that will be subject to sequence operation, the values immediately before
execution of the sequence operation are maintained. For example, when you want to execute a sequence operation for
the ISET value in NI mode, the PSET and VSET values from immediately before execution of the sequence operation
are maintained.

Comparison of normal-speed and fast-speed sequences
The normal-speed and fast-speed sequences differ in terms of operating speed (execution time), step setup items,
maximum number of steps, existence/nonexistence of pause function, and existence/nonexistence of a trigger-induced
pause reset function. See the table below for details.
Table 4.5-1
Normal speed sequence Fast speed sequence
Step setup item ISET value (NI mode) ISET value (FI mode)
RSET value (NR mode) RSET value (FR mode)
VSET value (NV mode)
PSET value (NP mode)
Trigger output Trigger output
Load on/off
Short function setup
Step or ramp transition specification
Pause function
Step execution time The time can be set for each step. However,
the range is fixed for every sequence.
1. Millisecond (ms): 1 ms to 9999 ms
2. Second (s): 1 s to 999.9 s
3. Minute (min and s): 1 s to 999 min 59 s
4. Hour (h and min): 1 min to 999 h 59 min
Pause function Available None
Pause reset by trigger Resettable Not resettable

Max number of steps 256 (*1) 1024 (*1)
No. of loops (*2) 1 to 9998, and infinite 1 to 9998, and infinite

The step execution time is set for every
sequence.
Millisecond (ms): 0.1 ms to 100 ms
*1) Maximum of total number of steps in entire program. For example, if 255 steps are contained in one program
used in the normal speed sequence, you can use another program having one step.
*2) Number of program iterations.
When the execution time of one step is shorter than the set TrTf in NI or FI mode, the actual current might not reach the
value set in the program.
At the fast speed sequence operation mode when two programs of one step or two steps chained each other are
executed at high speed, normal processing may not be done by the occurrence of a reception error for a message
through RS-232C. Change programming of the sequence or control the Electronic Load via GPIB.
When the execution time of one step in the NR or FR modes is shorter than 200 µ s, which represents both the current
rise time and fall time in CR mode, the actual current might not reach the value set in the program.
When you move from the step having 0 A to the next step, a current may rise after a delay of several hundred
microseconds and consequently, no current actually flows during several of the 0 A steps. In such an event, setting the
0 A step to about 1 % of the rated current reduces the delay in current rise.
