Bit Meaning
13 1 = Motorized
potentiometer, higher
14 1 = Motorized
potentiometer,
lower
Note:
If "Motorized potentiometer, higher" and "Motorized potentiometer, lower" both 0 or 1 at the same time, the
current setpoint is frozen.
15 1 = CDS bit 0
(only with telegrams p0922
= 20!)
Reserved
Setpoints
Speed setpoint A, 16-bit (NSET_A)
● Speed setpoint with 16-bit resolution incl. sign bit
● Bit 15 determines the setpoint sign:
● The speed setpoint is scaled via parameter p2000.
PCS7-specific setpoints (PCS7 x)
Depending on the configuration, KP adaptation values for the speed controller and
acceleration values or other setpoints, for example, are transferred here.

Description of status words and actual values

Overview
Table 10- 8 Overview of status words and actual values
Abbreviation Description
ZSW1 Status word 1
NACT_A Speed setpoint A (16-bit)
NACT_SMOOTH Actual speed value, smoothed
IAACT_SMOOTH Actual current value, smoothed
MACT_SMOOTH Actual torque value, smoothed
PACT_SMOOTH Actual power value, smoothed
316
Explanation
Only when p0922 = 1 or 352, otherwise reserved
Only when p0922 = 1 or 352, otherwise reserved
1: Command data set changeover (CDS) bit 0 is
active.
0: Command data set changeover (CDS) bit 0 is
inactive.
When p0922 = 1 or 352
– Bit = 0 → Positive setpoint
– Bit = 1 → Negative setpoint
N_set_A = 4000 hex or 16384 dec = speed in p2000
