8.4.3 Process velocity [SPEED]
Process velocity as % of nominal velocity
(Nominal velocity
nominal speed * travel per motor rotation).
valid until a new value is programmed.
When in speed control mode , direction of rotation is specified by the prefix.
SPEED value
Value: 0.0000001...100%

, a control parameter (P40..P49) or a variable
(V1..V39) e.g. SPEED .P40
Smallest steps = 0.002384min
-1
N005: SPEED 70 sets velocity to 70% of nominal speed.
The set velocity can be reduced using the analogue overrride input (X11.6)
(see start-up manual).
8.4.4 Acceleration and braking time [ACCEL]
Specification for acceleration and braking time .
without prefix: time specification for acceleration and decceleration process.
negative prefix: separate time specification for decceleration process.
valid until a new value is programmed.
Acceleration process can be specified using parameter P94 (see Page 75).
If a travel command is interrupted by STOP or BREAK, the STOP / BREAK – ramp
is not executed by ACCEL- but by the value defined as the acceleration time.
ACCEL value
Value: 10...65 000 ms, a control parameter (P40..P49) or a variable (V1..V39) e.g.
ACCEL .P40 (timescale = 10 ms)
The negative prefix for the decceleration time specification must be set
before the control parameters e.g.: ACCEL- .P40 (P40 > 0)
The time specified in ms applies for nominal velocity
(100%). The actual time is proportional to the velocity
selected. Meaning:
